I won’t command you to “Have a Happy Birthday” (any more than I would demand someone “Have a nice day!”) but I will wish that you do/did/will have one.
Your writing is not TMI. It’s real and honest. And totally familiar. It’s unfortunate that your psychiatrist couldn’t find a combination of meds that could at least take the edge off of the “pain” without unbearable side effects. It’s also not that surprising. It took my health care providers and me decades to come up with a combination that works for me. As I’m sure you’ve experienced but others reading this might not know, antidepressants and accompanying adjunct therapies aren’t happy pills. They don’t make you happy. The best they can do is keep the low times from being as deep as they might otherwise be, giving one the ability to either build up some psychic reserves or at least keep those reserves from being drained as quickly. Unfortunately, they all come with side effects. Most aren’t life threatening but are very annoying like the inability to achieve orgasm (period, nope not happening, almost...almost...fuck! It’s gone) or sweating if you do nearly anything. The most powerful ones have the worst side effects like uncontrollable tremors or feeling completely spaced out all the time.
I do hope your therapist is able to help you with the very hard work of taking control of your brain and retraining it to stop automatically sending you to places that are both unpleasant and untrue. That’s what I’m still working on but it’s quite difficult especially when outside events ambush me and drain all the reserves I’ve managed to horde.
I look forward to the day when you post that you’ve recovered enough that you enjoy writing fiction again. I remember when I used to check this site literally every day to see if you’d posted anything new. You have a great ability to suck me into your writing, making me care about your characters and enabling me to suspend disbelief. That’s something that most of the writers on this site can’t do for a cynical old curmudgeon like me.
