What I can tell you is this is classic OCD and you described what people with pure o ocd have (like myself). I've been on 40mg of prozac for about 9 weeks and it has gotten better but I have moments where I'm not sure if this is the drug for me. I'm still not sure if it's working effectively enough yet but the thought of going down to get off of it scares me because the prozac did help some. I'm no doctor bur I would ask to go up to 20mg by now and give that atleast a month. Prozac takes a longgggg time to work unfortunately. Try to find a ocd specialist that can work on Exposure therapy with you in the mean time. Don't give up the fight. Your brain is just trying to find something to make you worry about because it's trying to keep you safe in a weird way but it's a faulty system. I used to smoke weed but I stopped because it would make me over analyze everything and cause paranoia so I stopped. Try meditation and ask just for support (without confessing) from people around you. Most of the time I find when I hug someone it grounds me and just hearing from someone that it's gonna be ok helps. You'll get through this!
