Morning symptoms

This is just a list of what happens to me in the mornings. If anyone experiences this or knows what this is pleade tell me

Wakes up with an instant feeling of severe exhaustion and racing heart

Continuing to lay down and try to rest makes my heart race faster and breathing feels tight

Getting up makes me severely nauseous and breathing still feels tight

Consistent yawning but in a needing air way

Random coughing that makes me almost puke

Heavy brain fog and confusion for a few hours

I know I have dysautonomia but not what kind and am being tested for MCAS. I still have no idea whats happening but its making waking up in the morning absolutely miserable
