Hello, Nancys! Welcome to IAWP.
Ok, in order to be able to help you better, we need some more info. So, you took drugs for 28 years, yes? What antidepresants were those and what doses? Try to remember as much as you possibly can. What was the original reason why you had them prescribed? Was this depression, anxiety or something else? You mention starting reducing them one year ago. Please, give us more details about your taper. How big were the reductions? You tapered, then went on the drugs back again. Did you, eventually, go cold turkey on them? How big was the last dose/s of the drug/s. After such a long time spent on drugs, the taper should be done very very slowly and possibly one drug at a time to allow your brain and nervous system to adjust to the change.
Also, the brain injury you mention. Could you give us more detail on it?
All in all, our brains have amazing self-healing abilities, both in terms of recovering from blunt trauma and ADs drugs. Still, in the case of drugs, especially when taking them for such a long time, the reductions need to be done very gradually. Depending on what your taper looked like there would be two options; keeping it the way it is now (no drugs), or going back on at least some of them, stabilising, then reducing them very slowly.
