Did my initial fast taper (skipping days) permanently sensitize my nervous system?

I don’t know much now with that medication outside of it was my first medication I was prescribed at age 9. I have only just become aware of tapering protocols after 2+ decades on psych medications. I have only ever slowly tapered on Seroquel back in 2012 and done cold turkey with almost everything outside of that and a slow taper of Mirtazapine earlier this year upon finally developing an understanding about the importance of tapering. When I mean every other class of psych drug I mean that. I’ve just stopped cold turkey and come off and on multiple times and I’ve never really had any issues with them outside of the benzodiazepine class which I realise is dangerous to cold turkey, but in the past I was given little choice but to stop due to doctors leaving abruptly. But I was okay even the last time I went cold turkey on diazepam for 7 months although it was a walk through purgatory and I felt I was going to die, I didn’t. I cold turkey off SSRIs last year after decades of on and off use for PMDD. Actually, my doctor switched me to venlafaxine and the drug was so awful I was sleeping all day and unable to leave the house on the drug. so I came off it after 3 months and felt like I was sick with a severe influenza and looked into venlafaxine and realised how bad it was supposed to be. I ended up just riding that out for 7-10 days and feeling better after it was over. I know it’s not recommended but that was kind of how I discovered the tapering community. After that I vowed never to touch an SSRI, SNRI or tricyclic again. Ever. I think the power of neuroplasticity is underrated with this and I don’t want to sound invalidating and I think you will be okay, nothing will be permanently “sunburnt” and everything will heal as it should especially if you are resuming a micro taper. If you can find ways to naturally regulate your nervous system, like activate the parasympathetic part of your nervous system, that might be useful. Things like breathing, stretching, light exercise like walks, muscle release, massage, cold water, baths, acupressure and similar can be mildly useful although not a cure. It’s just a way to reduce the state of hypervigilance which is a form of sympathetic arousal.
