I'm glad you've been having some good days.

Yes, both male and female hormones do get a chance to chill and recover after coming off anti-depressants. You know, it's funny - I went to my doctor to get my hormones checked many months after coming off antidepressants. I was convinced they'd still be completely out of whack, yet they were actually 100% normal. You can get your levels looked at as well for peace of mind.
Truly, withdrawal is completely valid and happens, but I know from personal experience that it can last much longer than it needs to if you're focused on it. You have to forget all the horror stories you've read about. When I used to hit up withdrawal forums, I read that I needed to eat a perfectly clean diet every single day (never any cheat days or even a single gram of sugar), abstain from alcohol until I was 100% free of symptoms, exercise daily, etc. I spent a stupid amount of money on vitamins and supplements, and at one point was taking 12 to 20+ fish oil capsules a day. Literally, people were saying that it was the only way to recover from withdrawal, if you could recover at all. Now, I'm all about being healthy, but it seemed like my withdrawal symptoms just weren't going away no matter what. I was afraid I could never do anything again, which was sad because I do like to eat a few pieces of dark chocolate and enjoy some champagne with friends or a few pina coladas on the beach, and there are days when physical activity just isn't part of my schedule. I'm human! And you know what? My symptoms started going away once I gave up on the super strict lifestyle advice and started drinking alcohol (responsibly, of course) again. Why did this happen? I suspect it's because I had long recovered from withdrawal, and when I stopped fearing the horror stories and began having fun again, my nervous system finally calmed down.
I wasted so much time worrying about "permanent" withdrawal. It's not reality, it's a myth. The idea of permanence is a complete myth. Going through withdrawal certainly is no fun, but it's not forever. It doesn't matter how long you took the antidepressants, how long you tapered down, if you had to go cold turkey (not recommended but again, some people like me had to do it), etc. You will heal. I remember reading how long-term whiplash wasn't a major phenomenon in certain countries where people weren't as worried about it. Same goes for issues like RSI.
Mind-body/TMS symptoms can be caused by watching other people go through them, and I highly suspect that's what's occurring when people on these forums discuss permanence. This is not uncommon:

It's 100% clear that your fear of PGAD is what's causing these symptoms, as well as any ongoing withdrawal symptoms at this point. I recall you saying you've gone many days without withdrawal symptoms before, and that's absolutely a sign of mind-body/TMS. Your serotonin receptors sound like they're healed. It sounds like you just need to relax your mind - your body will follow. Addressing fear is critical. View this as an opportunity to overcome what you fear.
Per Steve Ozanich, withdrawal that someone "just can't get over" can be seen in this context, similar to an injury. This is why people continue to have symptoms even after their serotonin receptors recover - there is no such as permanent withdrawal:
Of course, we can injure ourselves. That’s called an acute injury.
Acute injury pain is a gift from nature to let us know we’re in danger. Whether you’ve touched something too hot or you’ve cut yourself, or you have an infection. Acute injuries help us to inform us.
The problem is if you’re in a TMS state, and you’re pushing yourself hard at that time. There are all kinds of relationship things going on in your life, and then, you fall as you did, the brain will become opportunistic, and it will attach itself to that injury, and it won’t heal. Months will go by and sometimes, years will go by, and this person can’t get over it. That’s the brain using it at that point.
Yes. You can hurt yourself like it sounds like you did but the body would heal in very quick fashion in days, weeks, or months if you’ve injured yourself terribly.
