long term damage to my brain from marijuana use

Hello everyone!  I found this forum in hopes that someone could either calm my fears regarded long term damage to my brain from marijuana use or confirm them. Here is some background information before I share  my withdrawal symptoms. I used to be an everyday marijuana user. For almost a year(November 2011- October2012) I was high all day, everyday. September 22nd was my first time trying 'shrooms'. It was my boyfriends birthday, we had been drinking and smoking since the early morning. In the late evening one of his friends gave him a bag of shrooms as a gift.  For the first hour everything was okay. Towards the end of the night I thought I was having a heart attack, could not distinguish between whether I was sleeping or awake, and eventually whether I was alive or dead. I finally confronted my friends and suggested that I be taken to the hospital. Everyone told me to calm down and that it would eventually pass. I called my mother in a panic and told her what had happened, she immediately came and took care of me until the trip finally wore off.  Every time I smoked pot after trying the mushrooms I had severe anxiety attacks. After a few weeks of gradually cutting down my intake I managed to quit. After being clean for a few days I realized how odd I felt. I felt like I was out of my body, like nothing mattered, and that I was losing my mind and myself. (I still feel that way now but to a much lesser degree since I've been sober.) in just, I feel high constantly. I quit smoking October 11 2012, and I post this now on November 11 2012.  I still feel like I'm going nuts. I worry that  I'm losing myself. I never have actually lost track of reality but I always feel on the edge.  -I have spuratic mood swings(that I'm starting to regain control of).   -Sometimes my dreams blur into reality.  -I drift into deep thought often and stare into 'space'(I did this before ever trying  pot but I feel out of reality and out of my skin now). - I feel like I'm very special and that I have a special purpose in life. (delusions?)  -I see trails(like slowed movements) -I see stars and spots(and in weird patterns) -I get really light headed sometimes(like I'm going to faint) -I live in past events often and have trouble living in the moment or in the future. - I have only recently begun to expirience regular or almost normal emotions.  -I am also tired all of the time. - I have become extremely paraniod about my health or having health issues - I have become very clean; germaphobic almost -I'm very forgetful and have trouble concentrating -I have a really bad headaches -did I mention, I'm forgetful?  I have quit regular schooling and an doing SAL. It's like ILC. In depending learning with booklets at home.  I am very active! I do aerobics and yoga every morning. I walk my dog twice a day. I do all of my school work at the library and walk to and from there usually twice a day.  I eat properly and am very health conscious. -I don't have any trouble making jokes or talking to people.  -I dont have hallucinations of auditory or visual sorts.  -I used to be very negative(past year); but due to my mother recently surviving a car accident against impossible odds, have made a major change to be very kind and positive.  -I think of myself as extremely intellegent, and extremely mature(these could be illusions, although I am told so quite often).  Two months ago I had an MRI done because of a concusion I suffered in August. Everything came back good and clear.  I have had my blood taken and analyzed many times over the past few months and everything is healthy/average. Since May 2012 I have lost 50lbs. I am 124lbs and 5'7. My family has watched me destroy myself over the past year but still they tell me I'm one of the smartest/kindest/well grounded people my age or older that they know. I worry that because of drug use I've ruined myself. I don't want to go crazy.  I've been diagnosed with anxiety and depression but the psychologist that I spoke with didn't ask me about my drug us prior to moving in with my grandmother(just did in September). He didn't ask me about my family or my life at home. He just asked me what I was feeling and gave me the medications I'm on that day. (cipralex) but I had a very bad reaction(anxiety attacks, insomnia, paranoia)  So he put me on new ones(pristiq, clonazepam, and temazepam) There isn't any cases of mental illness on my mothers side of the family but my father's grandmother and father suffer from depression. Everyone disagrees with me when I say I'm going crazy, schizophrenic, or psychotic; I genuinely feel I am losing my mind. Can someone relate to my story? Can someone ease my mind? Does this sound like the typical habitual smokers withdrawal story? Is this withdrawal? Will this go away? Could someone please give me advice?  I cannot live like this anymore. If this doesnt go away or gets worse I don't know what I'll do! I feel like there is a haze or fog around my brain. My worst fear is going insane!   Any (useful) comments would be greatly appreciated! thank you for reading, and for any response!    I want to feel normal for my 16th birthday this January!     Really regretful, afraid, confused, yet hopeful,                    A.K Ps I typed this out on my phone, so sorry for any errors or hard to understand bits!
