Missing a dose of medicine?

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. 🥹

I’ve been on Zoloft for 3 years almost for somatic ocd/anxiety/panic attacks and I slowly tapered myself off the correct way because I’ve been good for awhile and I felt like I was gaining weight from it. It’s been almost 2 months off the meds and NOW the last few days my anxiety has been so bad I’ve had no appetite and diarrhea and waves of panic is this me relapsing or a delayed reaction? Am I gonna have to be on meds my whole life because I really hope not :/ idk what to do I don’t wanna go back on my meds tho

So, I’ve had my OCD mostly “under control” for the past 10 years (I’m 44, battled this all my life). I’ve been on a high dosage of Luvox, but unfortunately it’s lost its effectiveness about 6 months ago. For the past five months I’ve also been doing therapy sessions on this site and have had a fairly good outcome. My main obsessions have mainly regarded around balance and symmetry. Anyhow, I’m in the process of switching to Prozac. It’s only been 6 days, so I obviously feel nothing yet. I made the foolish mistake of googling “What can antidepressants cause?” Unfortunately I found a very recent article of a study showing antidepressant users have a higher chance of getting ALS. There’s also older articles that say the opposite. But this one article FREAKED ME OUT. And I can only focus on the worst outcome. So, now I’m stuck in a repetitive thought pattern of getting ALS from the one medication that is supposed to help me. It’s absolutely terrifying and I haven’t experienced a health anxiety fear like this in years. I want to research more and more online, but I know this won’t help. It will only make things worse. Anyone with health anxiety have any advice on how to conquer this? I’m standing strong and not getting off my medication or doing any research.
