Undiagnosed with POTS: What Should I Do?

i’ve dealt with POTS and chronic fatigue symptoms since i was 13 years old, and for reference, i’m 20 now. i’ve seen all kinds of doctors who used to preach about my eating and exercise habits, even after i explained that i used to be a very active kid until this all started to set in. and now, as i’m still trying to find a doctor who will listen to me, they skirt around the word POTS and instead just describe it and give me all recommendations POTS patients are given (compression socks, increase salt intake…), but it’s discouraging that they won’t give me a proper diagnosis. without a proper diagnosis, i have trouble using mobility aids when i need to because i feel like i “shouldn’t” be. i have trouble talking to others about it because i don’t want to come across as faking it. and overall makes accommodating myself extremely difficult because of self-doubt. this post is mainly ranting, and sharing my experience hoping maybe someone else is feeling the same thing.

I wake up every morning with a headache and shortness of breathe, I feel ill just so ill. I was given the diagnoses with no help on what to do now, how can I help this feeling? I’m miserable

I’ve been struggling with POTS symptoms my entire life, I’ve fainted a few times but as I got older I learned the pre-syncope signs and would sit or lay in the middle of wherever I was. I want to seek a diagnosis, but I had a heart condition that I got treated for that I’m worried they’ll blame everything on. Should I try to find a different doctor?
