I started crying again. I felt like things were better, less triggered, no recollection of panic attacks since starting ketamine treatments. Then the tears came back and I feared I was regressing. Yet neurologically and physiologically these are two different states. Prior to ketamine I was in a collapsed state, dorsal vagal shutdown, where the nervous system believes survival is threatened and escape or repair isn’t possible. In this state the crying was uncontrollable and got to be constant. The hopelessness felt absolute and permanent. I am told I'm in a nervous system that is still wounded, still grieving, but no longer trapped in the same physiological prison. Ketamine restores flexibility to neural networks. That means emotions that were previously frozen or buried can move.
"Doesn't that sound nice? Now you can cry and let it out and heal!" No one said these exact words to me, but I've heard many versions of it. I don't have any expectation of "healing", as I don't believe we can heal from everything. There feels like an expectation of those looking on from the outside, that "healing" is an actual achievable goal, and if you don't then it's your fault. Though the intentions are good, it's not helpful.
Since things appeared to be going well, when the tears came back I was crushed and scared. My mother had sent a picture of a snowfall through a family text chain. My brother replied with a picture from the ocean saying he had a better view. This brother is also a therapist, who I reached out to when I was trying to get into intensive outpatient. He knew I was suicidal and going down hard. He doesn't know I'm now doing ketamine as he hasn't reached out at all to see how I am doing. He also got engaged over Christmas and is traveling the world with his fiancé. I am still unemployed, alone, and my one big goal when I got divorced was to travel and just an hour before this text I'd downgraded my Sky Miles Amex as I've lost flight status and can't afford to go anywhere. The comparison, looking at what I want yet just never happens for me, seeing a life I'd long for, it all just took me out.
First thoughts were that I couldn't go through this again. I thought of the months in collapse where I'd be screaming and sobbing, and it nearly ended me. But the crying did stop this time. I saw that though painful, I got back to my level set depression state and kept going.
I've wiped the tears once again. And I'll go on. But I'm so fucking tired of trying and living in this pain.
How ketamine works chemically in the brain
Ketamine works primarily by affecting the brain’s glutamate system, which is the main system responsible for learning, adaptation, and neural communication.
Most traditional antidepressants work on serotonin or dopamine and take weeks to gradually adjust levels. Ketamine works differently. It acts upstream, at the level of neural connectivity itself.
1. Ketamine temporarily blocks NMDA receptors
NMDA receptors normally regulate glutamate activity. Ketamine blocks these receptors briefly, which creates a controlled disruption in the brain’s usual signaling patterns.
This interruption prevents the brain from running its habitual loops in the same rigid way. (I'm a hard ruminator. Even when having a good time, in conversation, doing anything, the thoughts are incessant.)
2. This causes a surge of glutamate release
Because NMDA receptors are blocked, the brain releases more glutamate through other pathways, particularly AMPA receptors.
Glutamate is not a “mood chemical.” It’s a plasticity chemical.
It tells the brain:
“Pay attention. Something new is happening. Adapt.”
3. This activates repair and growth mechanisms
The glutamate surge triggers downstream processes, including the release of a protein called BDNF (brain-derived neurotrophic factor).
BDNF supports:
-
growth of new synaptic connections
-
strengthening of healthy neural pathways
-
repair of stress-damaged circuits
Chronic depression and trauma tend to weaken and prune neural connections. Ketamine temporarily reverses that pattern. (Temporarily. I just had my gut clench in fear of what happens when this ends. I wonder if you do enough of these sessions that it actually allows for repair.)
4. The brain becomes more flexible
For a period of hours to days after treatment, the brain enters a state of increased neuroplasticity.
This means neural pathways are less rigid and more capable of reorganizing.
Thought patterns that previously felt automatic and inescapable may loosen. Emotional responses may no longer trigger the same intensity of physiological alarm.
This flexibility allows the brain to update itself.
Why effort is not required
This process is chemical and cellular. It does not depend on conscious effort. (This is a hard one for me. I've been told for so long that my mental state is from my lack of effort while I'm always trying.)
You cannot “force” neuroplasticity through concentration or willpower during a session.
The beneficial effects come from the biological cascade:
-
NMDA receptor blockade
-
glutamate release
-
BDNF activation
-
synaptic remodeling
These processes occur regardless of whether your mind is quiet, busy, creative, or distracted.
Trying to control your thoughts does not enhance the effect. In fact, excessive effort activates control networks that can interfere with the nervous system’s ability to settle.
The brain repairs itself best when it is not being micromanaged. (I straight up laughed out loud on this one! I absolutely micromanage my brain.)
What you may notice subjectively
Because the brain becomes less locked into old patterns, people often experience:
-
more space between thoughts and reactions
-
reduced rumination
-
emotional distance from previously overwhelming material
-
increased ability to choose responses instead of being driven by reflex (Though mostly responsible, I'm a highly impulsive person. I've been judged harshly "Why would you do that?". I don't fucking know!)
These changes often emerge gradually, not all at once.
The key point
Ketamine does not insert happiness into the brain.
It restores the brain’s ability to change.
Once flexibility is restored, the nervous system is no longer trapped in fixed survival patterns. New responses become possible.
And importantly, this process happens whether you try to make it happen or not.
