Depersonalization for over a year, it seems like it is getting worse

I'm not sure if this is posted in the right section, but I hope this works.  I won't go into too much detail, but I've been stuck with depersonalization for a little over a year now and lately it seems like it's only been getting worse. I just turned 25 years old and I'm a female, if that helps.

I remember the day it happened after a pretty bad traumatic breakup. I started feeling fuzzy after a panic attack, like I had bad congestion from a head cold even though I wasn't sick. But, it went away after a few weeks, then it came back and has been with me for over a year.

A little about my depersonalization:

I'm forgetting things, I can't hang on to memories very well - especially details. I can't remember to do things unless I write them down because I'm so out of focus from the rest of the world. Everything is a dream state and even driving my car on some days is proving to be a challenge. I feel extremely detached from the world like I have no control and the things around me aren't actually happening. I cannot focus on what anyone is saying anymore. Even this post is honestly a little difficult to type and I have difficulty reading lately because I can't focus on the page or words. I get my sentences mixed up and I don't realize that I'm either not talking at all or saying something that makes no sense. I have mini panic attacks daily now because of how stressful it is and it makes me want to cry, but I've been pretty incapable of crying for a long time for some reason. I'm doing poorly at my job because I can't remember tasks I'm supposed to do. I get overwhelmed easily now and it's difficult because I do a lot of office work. That is just the gist of it, but hopefully that will help.

What I've been doing to fix it:

I've been on a pretty healthy diet lately, I've been exercising or at least stretching every single. I've been drinking lots of water. I've been trying to write more to bring my focus to the page. I've been to a lot therapy sessions. I've tried Lamictal 300mg, which did nothing so my MD took me off of it. Coming off of Lamictal, my depersonalization became worse. I tried Lexapro next...same thing. It didn't seem to make me worse after I quit, but I had no reaction to the medication. Positive or negative. I went to get tests done - those true/false agree/disagree psychology tests. The end result according to the test was that I have depersonalization (go figure), I suffer from pretty severe depression, social phobia, and I'm slightly masochistic. She simply told me to go back to therapy so they can continue on and better work with my results.

I'm just asking outside opinions on what to do or if anyone else has any similar experiences because I can't handle this much longer. It's ruining my life and everything I'm trying to do and it's triggering severe depression. I feel like I'm going in circles in therapy, although I know nothing is instantaneous. I'm going to continue going, but I just want outside voices and advice, please.

Thank you for taking your time, it's very much appreciated.
