I went to the emergency room and I got told they couldnt help me

Ive had probelms since I was 11 with my overaises and I havent ever been diagonsed or helped , Ive only ever had pain killers and its getting worst as I age. I got told off for going in. 11 years of it and nobody has ever taken me seriously. Im beyond upset and if I die I hope My family sues them all.
