I have talked about this before but I just need to vent more. 

Why I am anxious:  

I have been feeling really off almost all the time for about half a year now. It started very suddenly a few months ago when I randomly felt like I almost fainted. I did not fully lose consciousness but felt weak very suddenly and ended up lying on the floor of my kitchen for a while. However I had taken a small amount of THC that night so I chalked it up to that and moved on. however I noticed that after this I had frequent headaches and felt weak and sometimes even felt tingling in my face and a small amount in my left arm and left leg. I also sometimes could smell burring toast even when there was none present. I looked up these symptoms and many places on the internet these are early warning signs of a brain tumor. This cause me to be very anxious and go to see my doctor. My doctor told me that I was likely getting regular headaches that everyone gets but my anxiety was making it worse. She also told me smelling burning toast was nothing to worry about at all. I worked on my anxiety to get it under control and I did get it to be more manageable though it did not go away. this helped the headaches a bit but not completely and so my doctor told me it was likely just migraines. she gave me medication for migraines and they don't seem to help at all. She sent me to an eye doctor who gave me a test and the eye doc told me based on the test It was unlikely I had a brain tumor as it apparently would usually affect version more than the headaches seemed to. but even after all this I still get these strange feelings in my head. One reason I doubt they are migraines is that its a feeling of tightness and dizziness, weakness and other weird feeling that are hard to describe. But not intense pain. They are painful sometimes but most of the time they are just very uncomfortable. I told my doctor this but now she just seems to be taking it even less seriously. The intense discomfort is still intense enough that it makes it a lot harder to do things every day and recently it does feel a bit more painful like it is slowly getting worse. I have started waking up early after only a few hours of sleep with pain in my head now. And a feeling of slight dizziness head pressure and feeling off balance has become almost constant. I also just feel out of breath randomly for no reason sometimes and my face still tingles sometimes.  I am really really scared if I have a condition that will kill me but I really don't think my doc knows what's going on. I also have always had really bad death anxiety and am terrified of the idea of dying. I know it will happen eventually anyway but it still scares me and nothing I do can prevent this fear. 

Why I am having trouble trusting my doctor: 

They seem like because my condition is not intensely painful they are not taking it seriously even though It still causes intense discomfort and make it hard to do things day to day. I have also had issues with some other doctors taking care of family member recently. One doctor almost sent someone in my family home early by accident because the hospital was really overloaded. Luckily someone advocated for them to stay and it turns out they would have died if the doctor sent them home. But the ideas of doctors screwing things like this up because of how busy they are is very terrifying to me and makes it harder to trust them.
