Saw a doctor, WHAT DO I EVEN DO, feeling so defeated

I’ve had constant facial flushing for over a month, it really burns and hurts, and the last 2 weeks I’ve had constant adrenaline rushes and panic attacks and POTs symptoms. I finally saw a GP (I’m away from home permanently now) in rural Victoria (Melbourne).

He looked at me super concerned and said you need to see a cardiologist, and that’s a long wait. Literally Claritin, Zyrtec, Telfast (fenofoxadine) and Zantac (renatadine) don’t help my flushing at all I just feel so helpless and defeated my quality of life is so bad right now. He couldn’t even prescribe me anything to help with the flushing or were like
