I don't know if this is where i should post this but this is gonna be a long night

i feel like complete ****. I hate how i look. Im so ugly and not only that, i don't know how to make myself look better. I'm 19 and I don't know how to pluck my eyebroows, put on makeup, do my hair or dress nice. I'm so ugly and fat and I can't do anything abou it. I watch videos on youtube about how to apply make up amd Fhe girls are gorgeous but then i look at myself and know that'll neever be the case with me. I dont know about makeup brushes or how to style my hair. Everyday i wear black jeans with a " aaa" t shirt. I suck at being a girl and i hate myself. My sister is beautiful and she knows how to be a girl. Even with a kid she still looks awesome. People have always looked at her and then me and have said to me "what happened to YOU" i got the **** end of the stick. Im so ugly people tell me how i ugly i am. Im fat amd i suck. I hate myself. http://i932.photobucket.com/albums/ad168/maskela/ecf90f5f.jpg why am i so ugly??????
