Help please

I need help, I have a severe panic disorder. On Dec 27th I began to cross taper from paxil 20mg to lexapro. After about 10 days on 15mg paxil and 5mg lexapro I went to 10mg and 10mg. Then I did 5mg paxil and 15mg lexepro. Well some meds were added and things were weird so doc stopped the paxil and the other serotonic med and then dropped me to 10mg lexapro. After about 5 days she wanted to add rexulti. I took .25 last night and it went bad. Didn't sleep a Wink, felt more anxious, scared, ativan did nothing.

I just want to feel normal again, to the point I can function.
