Obession with girls and social anxiety disorder and anxiety disorder

I have obessions with girls. If I am out in public and I see a attractive girl I pretty much stalk her. If I get to no a girl and start liking her or get a crush on her I start to come on way to strong. Calling her way 2 much pretty much just obsessed with her also I get obessed when I see a hot girl when watching tv or a video or movie and everywhere I go out in public or watching something I am looking for attractive girl and if I see on in public and dont no her I will stalk her and I will become obsessed with her. I am humping 24/7 when I am by myslef. I am 20 years old and I have been doing this since i was 5 years old. I also have repeating behavior problems also when I get into trouble. Most of the time is my obession with girls. I will get the police called on me and when the police gets there they tell me I have been following a girl way to much and I need to leave her alone and I do and I move on. I am not manic or anything I am nice to everyone but I just have an obession with girls. If I don't think she is attractive or don't have a crush on her I can be her best friend. I also can't focus because all I am thinking about is girls. I guess you can also say I have delusional thinking. I am also parainod that people or out to get also. I guess it is cause of they way I act. I was woundering what is the best antischycotic medication. I have saw the other to post one here that are basically having the same problems as I am and I saw that risperdal help them but they got major side effects from it. I don't any antischycotic medication but I also saw where zyprexa, seroquel, and haldol where talked about. So can someone reply to help me with my issues. I also did the self test's on social anxiety and anxiety, depression, and ocd and the social anxiety test told me I had social anxiety disorder and the anxiety test told me I had anxiety disorder and the depression test told me I had no depression and the ocd test said also I had no ocd. I was pretty sure I had social anxiety and anxiety thats why I did the test. I also have alot of panic attacks but there was no self test on that. I was also was woundering what medication would best help with my social anxiety disorder and anxiety disorder and panic attacks that I can take long term. I am going to see my frist psycharitist on the 23rd of this month. I wrote this cause I feel like I am going crazy and I feel like I need someone to help me with this problem and find out what would be the best medication for me to take and also I am going to start going to therapy also.
