Dealing with Unsupportive Doctors

I don't trust doctors anymore sadly. I have to do all the research and work myself. I literally diagnosed myself with pots and had to prove it to my doctor. I kept a log of my heart rates from my apple watch and pulse ox. I saw a doctor a recently and she She asked me if I was "doctor shopping." She was my first doctor since my pediatrician and my pediatrician recommended her to me... told me my obvious symptoms of pots and dizziness upon standing "just didn't add up to anything." she said you have all these symptoms and they just don't add up to anything. She also said "you spend too much time on web md." Well yeah.. because doctors don't do their job and help me. She basically told me I was a hypochondriac. I'm still figuring it out myself how to be taken seriously but id recommend doing your homework and putting together symptom trackers, keep track of vitals if necessary, take pictures of anything weird and have them ready for your next appointment. Focus on what is bothering you the most because unfortunately dr.s get overwhelmed and don't help as much when you throw a list of symptoms at them from my experience. So keep a log of symptoms and look at patterns to see what occurs the most. They will want to know duration, severity (on a scale), types pain (be descriptive) ect.
