Hang in there. You're doing great. Losing control of your brain and body like this is truamatic and shakes your perception of what is normal and safe. It really is the case that you need to slowly rebuild your confidence as well as tolerance for day to day life. It doesn't happen all at once and you shouldn't expect it to. I remember having tremendous anxiety if my husband so much as went to the grocery store for an hour or two. I could barely leave the house. I also doubt that your fear and anxiety today is EXCLUSIVELY related to the thing you're actually anxious and fearful about. My best guess is that for now all negative emotions will feel amplified, that's how it happened for me. I could only think about the negative and scary things and focus on them obsessively, like constantly thinking about how my life was over and I would never be able to go out with friends to a restaurant much less go visit my family or go on a fun vacation. Except that it was the middle of the pandemic and nobody was inviting me to do any of those things. I would watch TV and see people going out and it would make my heart pound. Thankfully most of that is behind me and I think it'll still get better as life returns to some idea of normal. For the record even though I thought about it MANY times I never went on any other SNRI or SSRI, but I also never took Cymbalta for anxiety in the first place which made the withdrawal even more infuriating. The only thing I take now is a bit of Seroquel for the insomnia I developed (working on getting off that now) and L-theanine supplements which actually helped me a lot.
Good luck!
Thanks frog, this helped a lot. Hope you're doing well!
