This happened to me when I was 14. ( now 30)...... I smoked some marijuana and had a total out of body experience! Felt like I was not real, like I was in the beginning of dream state, but had no idea what was going on around me! Just in my own head was panic! And scared! This attack lasted almost a year! No one understood me, and I was scared to even tell anyone how I felt cuz I thought they would think I was crazy. I'm not ex actually sure what got me out of this, but I never again smoked weed nor have I done any other drug. I changed what I was doing, the people I was around, and tried to go back to what made me happy! At the time, actually up until last year, I had no idea this was even a panic attack. I read in a book about another girl who did the exact same thin as me and she was having a panic attack. I think you should try some calming techniques, do something that makes you happy, try to relax! Mine was being with my family, and not with the people that reminded me of this time! I also have God in my life. But to this day, I will not even drink a soda because of the caffeine! I suggest you stay away from it also! It's terrible for people with anxiety! I hope this helps, I just wanted you to know I get what you ate experiencing !!! It happened I me and you are not alone!!! Please let me know if there are any other ways I can help you!!!
