I had a really similar start with Zoloft. It made it really hard to concentrate and I felt like I wasn’t myself sometimes (felt really foggy and just gross sometimes). It might depend on how long you have been taking it. I’ve found that a lot of those side effects went away with time/ as my body adapted to being on it. It really does suck though I’m sorry it’s rough right now. For now it might help a bit just to lean into them a bit and rest as much as you can, and if the side effects don’t go away eventually and it’s bothering you it’s definitely with bringing up to your psychiatrist.
