Feeling sad after being cyber bullied?

[625]

Yesterday i asked this girl on instagram for likes for likes then she asked me for a shoutout for shoutout and i said yea then i suddenly got too lazy to do hers then she commented on my picture saying that i'm grimy and then blocked me. i went to her page and clicked on her ask.fm and i asked her why she blocked me and then she said that because i'm ugly thats why. then we went back and forth saying mean things but she hit a lowblow when she commented on instagram (my friend showed me) saying "I wanna know why the ***k this b**** look like a father bear. you gotta get your friends to follow me and try to curse me out LMAOOOOO. Hop tf off my cl**, trynna call me ugly. We both know thats a lie xD Why would you even attempt to say you look better than me? I'm disgusted. Your eyebrows look like scattered ants and you got ya lil orange friend to come at me. NAH. I know ya ugly a** lurkin so go ahead and go on my ask fm and talk sh**." then people commented laughing emojis and supported her and said im ugly anyway and they commented on my neck saying i have rolls and she asked if i wanted some butter with the rolls :/...
truth is i feel bad about my stomach and my eyebrows and face because my eyebrows ARE scattered kind of and i have like barely any and when i raise my eyes it creates lines and makes it seem like none are there. and my stomach it shows through shirts (the fat) and makes me insecure. Scared to wax my eyebrows cause it will look like i dont have any at all.
