Methylpred DP and anxiety

I am an 30 yr old female athlete who rarely gets sick i was put on this steroid due to trying to get over a head and chest cold.The third day of the pack i felt hot, nauseated,mean, went to the doctor he said just side effect and to keep taking it is now the 8 day the package was finished at day 6 i have high blood pressure and a ridiculous high pulse sitting . Anxiety has been horrible my chest hurts from it beating so hard im going crazy just waiting for this stuff to get out of my system never again

I was given this medicine for an adverse reaction to an antibiotic, I am not sure it was really an allergic reaction though, because I had no sweling. The antibiotic was prescribed for sinusitis and probably an ear problem ,that was supposed to be the cause for my first and only problem, dizzyness.
Anyway, I've been feeling really weird. First the anxiety, then the headaches, now a burning sensation in my neck and back and later insomnia. I can't differentiate what is a disease and what is a side effect. This symptoms are driving me nuts. And the worst is that my dizzyness is even worse. If I new the side effects s I would never have taken this.

This is my second day taking methylpred for lumbar vetrebra swelling which causes pain down my left leg. I know I've taken this before but don't remember how I felt on it at that time. This time it's like I'm on high speed. I hardly slept last night. I had to end up take 1/2 xanax just to get a couple of hours of sleep. My pain in my back and leg is already feeling better. I do sense some anxiety and a little heaviness in my chest but I don't know if the medicine is causing this since I do have little bouts of anxiety every now and then - which I think is normal.

No anxiety or leg twitching last night, but did have explicit sexual dreams so realistic I woke up mid-orgasm which is extremely unusual for this 40s female.
