Hey guys, I'm new here.

Just wanted to ask if you guys know, by any chance, how can OCD make one excessively jealous?
I'm asking this because I am so jealous and I can't get rid of it, always e-stalking and I can't spend a day without going to check 'her' facebook and I only feel relief when i actually do it...
And when I don't get what I want I have these unbearable suicidal thoughts and I end up cutting myself or something like that.
Someone who knows me well said I might have OCD, but I am very confused indeed. To be honest, I thought I was bipolar... I feel depressed, and then I'm great, and then I am just apathetic and then it all goes like everything. I have no self esteem and I give up on everything and I hurt the ones I love and myself. I used to drink a lot but I stopped it, which is really nice, because I would turn into a monster who would only remember things that have passed already.

Please, help me.. I don't know what else to do, especially with the jealousy problem, that seems to invade my dreams and hopes, and to lead my life.
