Ah I really feel for you. I know exactly what that’s like. I was in a similar boat and also dealing with a relationship breaking down. I’d tried several different ADs a few times before but always had an allergic reaction, came out in a rash etc.
My GP said we should try again at a very low starting dose of Citalopram and this time I didn’t get a rash. My mood improved amazingly within a couple of weeks, and I didn’t suffer any real side effects (except a slightly reduced orgasm, but still able to, and still enjoyable!). I was prepared to feel worse or have physical side effects etc but was lucky not to.
I tried coming off them after a few months, had the odd headache but nothing unbearable. But I did get snappy and irritable again, so went back on them. I know that snappiness may have passed if I gave it a while to settle but I didn’t feel the need to stop taking them, it was more just a case of forgetting to collect my prescription and thinking I may as well not.
I know some people get awful withdrawal - I know someone who got what they call ‘brain zaps’, electrical shocks in the head several times a minute. Which sounds horrendous. But there are ways to taper off them and avoid the worst of the effects once you’re done taking them.
Went back on and after a while doubled my dose, again no bad effects, still able to orgasm, mood much improved. I can still cry when needed. But I don’t weep at the drop of a hat anymore!
I have no plans to stop, but if at some point I do, I’ll just be glad they got me through a really difficult patch and would always recommend people at least try them, with the caveat that people around you know the increased risk of eg suicide etc when you first start taking them and keep an eye on you. Not something I ever had, but I know it’s a symptom of your brain chemistry changing so something they have to mention as a possible side effect.
I know loads of people who take them happily with no plans to stop, so if you do give them a go I hope they work well for you too. If not there are other things you can do, therapy etc but with the cost of that compared to just settling your anxiety to enable you to deal with the issues in your own time, I think ADs are a god send
