Have I gone crazy,or is this supposed to happen?? HELP?

Around the end of July 2010, I decided to try MDMA and shrooms together for the first time. The only drug I have ever tried was weed in my life. My best friend brought them down and I was very excited. First, we took the mushrooms at about 2 in the afternoon. We were sitting in my house and we were very comfortable and everything was fine. Two of our friends,who have tried both before ended up coming over so if we started freaking out, they were there to calm us down. Then, around 6 pm we took our first MDMA pill. It was fun and all I wanted to do was jump around. At around 7-7:30, I started getting panicky and thinking that they were all conspiracing against me, so i locked myself in the bathroom with the lights off. All I wanted was to be alone, and they wouldnt let me. One of my friends who had shown up hadto keep coming upstairs to calm me down and tell me everything was okay. Eventually I realised that it was and I knew why I was the way I was. So, I went back downstairs with him to see everybody and hangout. Well, I started drinking beer and smoking so much pot, that by the time I took my second pill, I was tripping so hard. I would walk in my house and I felt like I was a doll, and somebody was controlling me. Or, I would sit upstairs by the bathroom door and minutes felt like hours, and hours felt like minutes. I was so scared because everything I have ever thought about was all coming out in a wierd way. Things that I have never told people, it seemed as though everybody was in my head. Everything was playing out very weird and it seemed as though llife started making sense. I felt as though everything was planned out, and everytime we brought up a friends name, I kept thinking that they were hidibg in a room and thats why the door was closed. I never went in that room. I thought that I was being watched, and that every decision I made would have a consiquence. I was terrified to do anything. I hadto go to the bathroom, and i held it for so long because I thought that the second I sat down, something was going to happen, or somebody was going to come in. I was terrified. It wasnt all a bad trip though. I did have fun, just some of the parts I wish I didnt remember. But, my main question for this is; Everyttime I smoke pot now, I get the same feelings and thoughts. I'll be standing doing something and forget what I was doing. Or while I'm doing it, it feels like I have a bunch of different people's conversations going on, when I'm by myself. I have a bunch of crazy thoughts going on in my mind and I'm not quite sure what to do. I've looked evrywhere, and nobody has answers. These thoughts are only when I smoke pot, which i try not to do because I'm scared to. I get shaky, and my heart races way to fast.
What is going on? Is this happening because of the mushrooms and pot mixing? Or the M and pot? Or the beer? Or am I just developing Schizophrenia? I don`t know what to do anymore.
