Fed up of the shaming

Since I was 12 I've worn baggy clothes, boring colours (mainly black or grey) and I've got myself. I've been bullied constantly and when I try and make an effort the bullying just gets worse. I feel like I can't win. today I went out and bought skinny jeans, tight t-shirt and fitted jacket. I'm 25 years old and I've been scared for people to see my proper body shape for 7 years. I am going to go out, head up and try and find some inner confidence.. wish me luck.
