Social media makes me feel so ugly

I’ve been wanting to get this off my chest cause it’s been bothering me for years. I hate social media. Instagram, Facebook, Twitter, and even snapchat all make me feel horrible. Why? Cause I’m constantly seeing the best of other people’s lives, seeing them hang out with their friends and be told that they’re pretty. I don’t have any social media aside from Instagram (at the moment) and let me tell you...I’ve NEVER been told I looked pretty on any of my photos. EVER. I’m constantly seeing other girls being told things like “YAAAS YOURE A BEAUTIFUL QUEEN” and “OMG YOURE SO PERFECT CAN I BE YOU??”. I wish I had that same kind of support. I wish people liked me and thought that I was pretty. But I guess people will always think that I am ugly and not good enough. I’m 19 now, but when I was around 13-16 I received TONS of negative attention on social media. People would constantly mock and bully me. They would make fun of every single aspect of me and it hurt so bad. So I’ve never really received any positive attention on any social media. I wish that people liked me and thought that I was pretty. I know that I shouldn’t care what other people think, but at this point it just hurts to see other girls constantly being told they’re beautiful and gorgeous on Instagram and Twitter. Idk, it’s just bothering me a lot. Oh and I should add that recently I was in a group chat of like 10 other girls where literally every time a girl sent a selfie they got complimented...except for me. My selfie was never even acknowledged and it made me feel so horrible. Anyway...I must be really hideous. Does anyone wanna talk to me about it?
