I'm just going to jump straight into it, since I suck at introductions.

I am a 23 year old university student, getting my degree in comp sci (which was my first mistake - I don't really like it, but I have to finish it now, I have enough debt as it is, and my parents already consider me a failure, I don't need to give them another reason to be disappointed in me and shit on my self-esteem some more). I exercise moderately, I'm a little bit more muscular now that a year earlier, but I'm still skinny as fuck. Plus, I'm pretty sure I'm below average in looks, since when I got bullied in school, my appearance was what people mocked me most for, and I'm pretty sure the "ugly duckling to handsome swan" thing doesn't happen in real life.

I think I'm decently intelligent, but I'm probably dumber than I hope. I basically have zero friends now, as the only social circle I ever had was as a result of my family socializing, and they have all moved on. I figure they didn't like me much anyway and were just being polite, I was always the weird and nonathletic one and I was too much of an asshole at times in a desperate attempt to be "cool". Never had a girlfriend, never had sex, never kissed a girl, never even got close to any sort of intimacy. I can talk to people alright most of the time, but I can't make new friends to save my life, even though I participated in several clubs and activities hoping to do exactly this.

I know what you're going to say - "Just approach, bro!", but I can't anymore. I've tried, goodness knows I've tried, but it seems like every girl I try to talk to has a boyfriend, or just plain ghosts me after a decent conversation or ignores me in favor of another guy. I'm fed up with always having to take the most difficult path that yields little fruit, I figure maybe having a social circle will finally help get laid, but I have no idea where to even begin. I know what I want, at least, I want to get a girlfriend, I want to have sex. I will admit it, I don't have the highest self-confidence, I frequently resort to pauses in conversation because I have to think of what to say, I don't know how to close, how to escalate or anything to do with getting girls.

What the hell do I do, seddit?
