I am haating life and my life is going nowhere, How do i get out of this hole?

[Kawasaki]

I have just turned 20 and i am starting to see no hope for my self at all in life. I have a job that i enjoy but thats about it. I have a few friends but i like them and i dont think they really like me because if theres ever a party or any activitys that they go and do im very lucky if i get told about it or invited. i know some of you will say they are not true friends and to leave them but if i did i would have no one and i mean no one. I am a virgin and have never even kissed a girl, i cant talk to girls and im really bad when i meet new people guys or girls because im shit at making conversation so it always ends up in awkward silence. I live in a flat with people way out of my age group so i dont really talk to them and find my self spending a alot of time in my room. I am basicly going to work five days a week, coming home and spending the rest of the time in my room and then despratly hoping i will get invited to go do something with my mates on the weekends (i used to txt them and ask what they were doing and they would say nothing and then mid way through the week i hear that they went jetsking or something) nd if that doesnt happen i will go clean my car or just go to my parents house. I know that half my problem is i have massive social problems and i my head i always think people are judging me. An example of this is i always try and cook and eat my food at the flat when know one is around so they do think what im eatting is weird and its never weird food but i still do this anyway( i know im nuts) Basicly i cant see my lift ever going anywhere except for me loosing the friends i have left and then winding up living in a house by myself and hating my lift more than i already do.
