i have been getting mild headaches lately and started feeling dizzy. i feel panicky from it now. i always think the worst. i fell from a window about two months ago and i broke my foot in 8 places. im fine apart from that and my mental health. i always think when i get headaches and dizziness that there isn't enough oxygen getting to my head. is that possible. everynight i put my fingers down my throat and make myself sick its a terrible habit. i got a few problems with derealisation and anxiety. my head just doesnt feel right at the moment and i always think brain tumour or is there something seriously wrong with me any advice would be great. thank you. richard. aged 24.
