Suggest Treatment For Anxiety Disorder , Chest Pain And Dizziness

Hi everyone :).(sorry, for my english. It isn't my first launguage) My story is long but i'll resume it the better i could cause my english is not good enough yet. i'm a 19 years old psychology student (i'm a girl) and I have an anxiety disorder and i'm obsessive compulsive specially with my health since i was 14. I've always felt sharp pains in chest, arrythmias, constipation, weird feeling in my throat, pressure in my head, headaches, numbness etc and i've had a crisis since 2 years ago, i had a ct scan at that moment and it was normal, my blood tests are also normal and my ECG and ecocardiography are 'excellent'. But the last months/weeks i'm getting worse my head is heavy when i move it or bend down mostly on the right side and sometimes it hurts, i feel nausea, drowsiness, dizzines, numbness in the right side of my face like my eyelid is heavy and i'm afraid i'm gonna have ptosis. I also feel weakness on my right hand. Can it be a brain tumour or just my anxiety disorder? I'm really scared because someone of my neighborhood had the same symptoms and it was a brain tumour and she died in 10 months :( And all stories i found in the web are freaking me out because it always has to do with brain tumours, aneurysms, etc HELP ME PLEASE (hope you had understood)
