Will I be alone forever?

I am 17 and I never been in any kind or relationship in my entire life. I have never had a kiss or a hug and mostly I am very shy and quiet. I am a nice person but I am introverted and socially awkward. The reason why I ask this was because lately I have been observing around my high school and it seems like everyone I know is currently in love with someone. I feel like I am the only one that is single most if the time. I never get out and I spend all my time on the internet on online forums chatting with internet people. I want to have a girlfriend but since I feel Like I will never get one because many people say I don't look attractive they say I need to gain more weight or clear up my acne (that will never go away) and get better clothes. I never want to do this because I like the way I am except for the acne. I feel like I will be single forever what are some good ways I could cope with being single?
