i have been having shortness of breath for about a week now, thinking it was anxiety (I get stressed about things very easily), but last night around 2am i woke up with my heart racing, sweating, feeling super nauseous and trouble breathing. I thought I was having a panic attack, felt like i was dying. but today my nausea is still there and i found this small rash on my stomach and still have a hard time breathing. I dont know if my anxiety is making me imagine these symptoms but i just wish i knew what was wrong. I am very afraid of hospitals and doctors and just thinking about it makes my anxiety worst. also i have this bump on my palate (in mouth) that feels bruised and i saw that was a symptom of mono. is this just a case of bad anxiety or could it be something more serious?
