I feel really bad today

I don't know where else to post this and i need happy thoughts. I just started hrt this past week. I am on antidepressants and anti anxiety meds which I will wean off of after I'm stable on hrt. I got a covid vax this morning. dr ordered me to do a 6 day round of prednisone for an injury. today is the first day of it. prednisone, previously, made me feel AWESOME every time in my life ive had to take it.
I feel so fucking anxious I think im going to crawl out of my skin. ive taken 2 hydroxazine because holy shit I'm jittery.

kind words or any advice my people?
