What is a good medication for panic disorder in someone with CPTSD?

Hey y'all, I discontinued fluoxetine not under a doctor's guidance after about a decade on it about two-ish months ago. I am realizing now what a thoughtless decision that was. For the past couple weeks I have had debilitating panic attacks (sent me to the E.R. twice) that have increased in frequency from a couple a week to now one to two a day. Now I'm having feelings of anxiety all day in fear of the next attack and I feel as though I just can't function.

I am seeing my doctor tomorrow and have heard Paxil is effective and works faster than other medications, but I wanted some input from others who live with both disorders regarding what medicine they have had success with before I push too hard for Paxil. Thanks.
