This is very true, AD lower you sex drive completely; I have been on Paxil for 3 months and also asked many people who are on AD and almost 100% told me there is no 'motivation' for sex at all...
Honestly, you have a lot on your plate before thinking about sex. It's hard to tell if a med has caused it, but I can tell you deep depression will kill your libido, especially if you've been suicidal. I'm on a myriad of meds, and my libido is great. So hopefully you can get stable again, and become more balanced, then once that's happened, I would address this with your psychiatrist. I hope you feel better soon.
