A life controlled by panic

So maybe writing like this will help with everything, because so far nothing else has.
Panic attacks have once again taken over my life. I started having panic attacks at 15 and at 17 was diagnosed with a panic disorder. I took prozac for like 4 years, and it helped and then all of a sudden it stopped and the downwards spiral started. Even after going back to the doctor and switching to zoloft and xanax, it's getting worse. I can't go anywhere or do anything. My house was always a safe place for me, and it's not anymore. I've had to drop classes this quarter, I can't handle being at work, I can't even take Hailie for walks. I want my life back ! but I don't even know where to begin. I've been on the new medicines for 3 weeks now, and it's still getting worse. I'm so tired from them that I'm anxious all the times, so whenever i'm not actually having a panic attack, I feel like i'm about to at any time. I have panic attacks about the thought of having a panic  attacks.........Everytime I go somewhere I have to know the fastest route to get out of there in case one starts...I WANT MY LIFE BACK!
