Convinced I have a brain tumor or just my anxiety??

Hello I probably may sound silly and irrational but Im starting to believe I have a brain tumor . For a while now ive experienced this sudden smell of smoke that will just randomly come out of nowhere and leave in seconds I googled it and a whole bunch of things showed up like seizures, tumors, epilepsy.. etc now im so scared and anxious im creating symptoms. But now I put things together and am convinced because a while ago I was experiencing ringing in my ears for a few days and it went away as well as sometimes vision disturbances and being dizzy but the dizziness I have experienced for a few years now as well as headaches so these two dont worry me as much. I read its symptoms of seizures? I have never had one Im pretty healthy Im 19 and doctor always has said my labs are fine. I know Im young but its not impossible to have a tumor at a young age... What should I do ? Im scared to go to my doctors and tell them because what if I make them concerned with these symptoms and tell me I do have a tumor but Im just convinced.. So sorry its long I just hate this & need to express these concerns. Im just always convinced I have some type of cancer or tumor ): Has anyone experienced something like this and turned out fine? 

you have health anxiety for sure x I’ll pm you something that will show all your symptoms are anxiety most likely x

but go to the doctors too as it’s better just to make sure x even if it’s just to put your mind at ease :blush:
