Depersonalized feeling after much stress

I am 19 years old, and have been through a lot lately. I was completely fine before my use of the drug 5 MeO-DMT. I do not actually think I did enough to even experience what the drug is intended to do, but I did have a major panic attack. I felt as though I was on auto-pilot, and as if I were not in control of what I was saying or doing. It FREAKED me out. Ever since then, I have just felt off and been different. I broke up with my boyfriend who I had stayed with even after finding him talking to other girls on the internet. And after I had the panic attack, it's like I took care of everything I needed to take care of, which included leaving him, moving back in with my family, got close to God again, and getting back into school. Before the panic attack, I was a marijuana smoker for almost 2 years, and most of the time it was daily smoking. However, after my panic attack, smoking marijuana makes me feel even more depersonalized and anxious. It seems that each time I tried smoking after it, which was like 15 times, things just got worse and worse. I've been having symptoms of depersonalization and anxiety ever since the panic attack. I've felt that my body wasn't my body (but I know it is), that my words were just flowing out without no real intent behind it (but they weren't things I wouldn't normally say) that I wasn't actually who I was when I looked in the mirror, that the things that are taking place around me aren't currently taking place (as if it were in the past or something), disconnected from my emotions, and when I would hang out with my ex it would feel as though I were in the past (this happened once before my panic attack ever happened), when people would talk to me or about me or look at me I wouldn't really feel the impact of them doing that and just not the same as I used to when people would do this, I would also not feel a difference when I walked outside from being inside or vice versa or between when I was in a car or not, I just wouldn't like feel the difference in environmental change, my family didn't seem like my family (but I know they are), they would sometimes look unfamiliar to me (kind of like when you see a celebrity in real life and you just can't believe it), and a few other things. However, those have mostly subsided. I also felt like less of a person (but my relationship was co-dependent with me doing everything for my boyfriend), and we were together almost 24/7, and I also felt like there was just a dark hole in my mind after the panic attack. I would feel very anxious if I weren't with him when we were together, and I would be quick to finish doing whatever I had to do so I could get back to him. I recently or back on Zoloft, which I took from the age of 11-19 for PTSD, OCD, anxiety, and depression. I stopped taking it in March 2014 after a shroom trip that made me feel as if I could control my OCD and anxiety without Zoloft (which I was able to do until the panic attack) (I've done shrooms 3 times, and the first time I was still taking Zoloft, and it felt as though my soul rushed into my body, I was COMPLETELY connected to my mind and my body, and I was fully aware of everything in my life). The first time I did shrooms, I had moved to Flagstaff for school, and when I was on shrooms, I just COULD NOT believe I lived in Flagstaff. But now I feel disconnected from my mind. I have thoughts, and I talk and everything, but it somehow seems like I'm not inside my mind. It's kind of hard to explain. But are these typical symptoms of anxiety, leaving a 2-year co-dependent relationship, depression, panic attack, etc.? F.Y.I., my boyfriend was like my drug-fix, and I hardly ever saw my family wen we were dating. We have been broken up for almost 3 months now but kept talking and seeing each occasionally after we broke up. I also ignored my needs most of the time when I was with him, and I changed all my interests to his so that we would be more compatible (I know now, that is SO dumb to do). Also, what can I do to feel more "inside" my mind? Ever since the Zoloft started kicking in, it seems that is when I started feeling kind of outside of my mind.
