Health Anxiety Ruining my Life

I’m losing my mind. Health anxiety is ruining me. It started with worry about a brain tumor, (getting a MRI tomorrow). And I still think I have one in my cerebellum, and I’ve been having heartburn, indigestion, and a marble feeling in my throat. Now I think I have stomach cancer. What do I do? This is awful. And I’m so stressed and worried about my health. I can’t keep going back to doctors to have them test me for every cancer under the sun 

I have health anxiety also and understand what your going through it all started with burning skin that they couldn't tell me what it is had all tests and an MRI and they found nothing.. still suffered with it my health anxiety has made me very ill was never out the doctors with it put on anti depressants which made me worse.. a was getting better am a year in now and the burning is back but it's on my face which is making me anxious again.. feel the vicious cycle of health anxiety kicking in it's horrible.. a can't go to doctors as waiting on results make me worse.. but yeah I understand what your going through.. also had pains in stomach and they put a camera down and it just turned out to be inflammation of my stomach.. the Brain is a powerful thing unfortunately and convince you of anything and even give you the symptoms to prove it... try not worry yourself sick again I know easy said than done.. but the months and months of worrying I've done for nothing is ridiculous.... hope you feel better soon.. another thing if you don't hear anything right away with your MRI it's been clear as they don't contact you.. they just give everyone a follow up and tell them it's clear there.. just so you don't worry yourself after it waiting.. no news is good news.. 

Thank you so much. This has been so hard. Did you also think you had stomach cancer?
