Me and my best friend who i loved so much went to a rave with me six month ago. We both took a lot of mdma and she overdosed. I am not the same person now. I am constantly sad. I hate what i look like am failing cant focus. I am constantly on the verge of panicking and i am obsessed with my weight. Everyone tells me im skinny and i see it but i cant eat. I just freak out even more. I think i have ptsd because i will have panic attacks and i had one the other day when i went to a concert. I cant do anything because i feel like shit.
