Go see someone. You need some help man because that shit isn't normal. As far as the girl, go talk to her. Be friendly, mr. outgoing but not overwhelming. Let her know you exist and that you are this fun guy. But get past this depression shit or your not gonna look like a fun guy to hang around. Women aren't attracted to people with problems, she's going to be attacted to a man that knows what he wants and is fun to be around. Go see someone, get some meds, and look forward to nailing that ass and be confident that your going to do it. And it will happen.
