Can the medication cause weight gain

I know this isn’t directly ocd related but I feel like it’s got to be a shared experience between a lot of us. When I ask in fitness groups no one seems to have anything to offer. Anywhooo I started celexa in October I believe? In January I started going hard in the gym and tracking my macros to a tee. In the past I have done this and got really fit and muscular. This time around the progress has been going at a snails pace. I almost feel like progress has even haulted and hasn’t even been that long. Anyway I really think I have a good amount of knowledge on this stuff and mostly want to know if anyone has had this experience after taking celexa? I can’t think of another factor that it could be. I would almost like to get off of it because of it. I hate to sound vain but with the extra weight I feel depressed and uncomfortable. I’m putting in soooo much work and seeing the results but like I said it’s going ridiculously slow. Any advice for this kind of thing? Thank you :)

So I have been diagnosed with GAD and OCD and my psychiatrist prescribed me with zoloft 🤔 but I dont know im really hesitant to start medication because im scared of the side effects and ik afraid of relying on a medication for a long time. Does anyone else take zoloft? What is it like? Any side effects?

I am having an appointment with my psychiatrist this afternoon and I am obsessing about what to do with my medication. I think it’s also very ocd like obsessing. I am currently on 30mg mirtazapine. Ive been on this for years (because of insomnia, anxiety and depression) (15mg) and after we tried to switch to another (amitryptiline) because of nerve pain, I went down the road of insomnia and later on ocd again. So I am back on mirtazapine, and weaning off of the amitryptiline. This is/was a very traumatic experience. Because the switch caused a mental breakdown. Now my psychiatrist has mentioned to up the mirtazapine to 45mg. And my obsessive self has done a lot of research and a lot is saying that the higher the dose, the more you can experience anxiety. And for ocd it’s obviously not the first choice. I am obsessing all morning about it. I am too scared to go up. But I am also too scared to try another and to wean myself of off mirtazapine. I feel stuck at this point. Taking two meds is also not something I want. I could really use some words of encouragement right now I think. 🥹
