SUBREDDIT: r/relationships
TITLE: I [20 M] am 6'3" tall and have never had a girlfriend - or even much attention from women at all.
POST: Gonna keep this short : I'm a 20 year old dude who has never had a girlfriend. I find that generally women tend to ignore me. I'm a university student so theoretically am in the best time to meet new people but it simply isn't happening. Been feeling a little bit lonely over this lately. I've been told before that I am an extremely friendly person, so the fact that my personality isn't too shitty makes me wonder if there's simply something wrong with my appearance (AKA girls find me ugly). I've become very bitter when by myself.

I'm a very tall 6'3" and lanky. I hear a lot of stuff online and elsewhere about how girls supposedly like tall dudes. See for me this is like a curse - I've become very self-conscious about my height, to the point that I wish I was shorter. Honestly feel like being so tall and skinny makes me intimidating to girls. In addition, maybe being a minority (I'm black) also severely limits my dating pool and contributes to people's perception of me as unattractive. Even at this height I absolutely NEVER get 'checked out' by women - not even so much as a smile. Quite the opposite, many girls truly act like they are repulsed be me. At this point I just am starting to think that I'm the complete opposite of what the majority of women find even remotely attractive. Just feel kind of undateable right now.
TL;DR: 
What exactly can I do to improve my self-esteem and crazy beliefs about myself, and realize that I AM deserving of a healthy relationship?
