Will I spend the rest of my life alone?

I read a problem that was sent to a magazine about a lady who was 34 and still a virgin..and I thought 'My god, that's gonna be me in 14-15 years'...that thought scared the crap outta me. I'm 20 years old and I've never had a boyfriend or had any ual experiences at all. Although I have no problem attracting guys, I'm just really fussy when it comes to potential boyfriends, the recent guy I met had a speech impediment (which annoyed me and I never noticed the first time i met him cos we were in a club and the music was loud) and the second night we met up he told me all about his life and problems he has with his family...I thought it was a bit too much and I felt overwhelmed so I told him that I'd just like to be friends. I'm scared that cos of my 'fussyness' I will end up alone for the rest of my life...I'm actually preparing myself for a life of singledom cos the way I'm going I'm never gonna meet someone or lose my virginity. Also as I am a size 14-16 (uk), I push guys away cos I'm not confident enough about my body to have boyfriends. I'd love to have body confidence but I just don't and the thought of having with someone at the size I am now repulses me, the thought of someone who actually would like to have with me...Ithink they're nuts! I hate looking at myself in the mirror.Although I love being single the thought that I'm gonna spend the rest of my life alone scares me and I'm considering going to therapy cos I don't think it's normal to feel like this or normal that I've never had a boyfriend or had . I'm writing this here cos if i talk to my mum or my friends they'll think im being stupid and brush it off when it is a genuine concern for me. Can any of you give me some advice..cos I feel like I'm gonna have a panic attack about facing life alone. Please help me xxx
