Last friday, April 10, I took ecstasy for the first time. (but some people were telling me it was thizz). I got over the effects after like three days. But last night I smoked weed. But I didn't get high. The effects of the ecstasy came back. Not the good effects either. They were all the crappy feelings. I was getting panic attacks and my heart was almost pounding out of my chest. I didn't go to bed until 2. That was because my stomach hurt and i was scared to go to sleep. Today, my stomach hurts and im really tired. I have a headache and it feels like my brain burns. I only intended on trying it once. I gave up weed due to what happened last night. I'm scared that I could die. But that could be the panic attacks. Any advice?
