I totally get what you mean about not feeling like yourself.
In 2007 I had my first big panic attack. It took around a year or so to recover fully. For a long time I felt as though I was in a haze. Everything felt like a dream, people didn't have depth, the air around me was frightening. I would wake up in a panic every couple of hours at night while I slept. After a short stint of agoraphobia thereafter, I pulled myself out from under the covers and out of bed and got help. I was taking Citalopram and was also prescribed Lorazepam to help take the edge off. Finally, through time and proper medication management, I started to feel better.
But here's the kicker, and something extremely important for you to remember in your recovery. I realized that a good amount of my anxiety after the attack was me psyching myself out. I was afraid of having another attack and falling back into the same thing again. I then chose to not be afraid. I decided that I was NOT going to have another one and I was NOT going to be afraid anymore. While our fight or flight responses in overdrive cause anxiety, we are the ones who aggravate it. You must choose not to worry or fear having another attack. Learn to accept what you cannot control and control what you can, through thinking logically and pushing away your fears. I often find myself scolding myself if I feel like I'm getting anxious. I remind myself there is absolutely no reason at all to feel this way, that its just my stupid brain again making a mess of things and to refuse to let it take hold of me.
There is one thing I have learned through all of this and it applies to each and every human being. There is a big difference between fear and anxiety. If you can decipher the difference, choose not to fear anything and to manage your anxiety, then you can live a normal life.
