Hi Im 26 Year Old Female, I Suffer From Really

Hi im 26 year old female, i suffer from really bad stomach,pelvic,back and leg pain, its all connected to the one pain if that makes sense. I recently went to the hospital because the pain so bad, the doctors couldnt find anything wrong and have now referred me to a gynacologist. I have abnormal cells and have done since 2012, i had many appointments to go for a colscopy and i didnt attent any of them. Last year i was constantly having diheria which hasnt went away, doctors said it could be ibs and i was prescribed medication that hasnt worked. I have gained over 2 stone in 6 months without any change in my diet, most days i feel constipated, bloated and very tired and weak, two days ago my body feels very soar mostly in my back and pelvis
