I'm a teenage girl, I'm a raging hypochondriac aswell. Couple weeks ago i was convincing myself i had bowel cancer but now I'm convincing myself i have a brain tumour. So basically I fainted the other morning but My parents seem to think it was because i was sunburnt and came out a steaming hot shower but i'm not sure because ever since all i've felt is dizzy and disconnected from my body, and lightheaded and i keep forgetting little things. Also after i fainted i had tinnitus in my ear. I tried to tell myself i'm okay im just worrying because i can still go out and do things, but it's past the point of convincing myself and i'm so worried and stressed can anyone help?
