panic attacks and fever

recently i had my first major panic attack due to a bad drug trip. it was my first time doing drugs, and since then i have had panic disorder and am convinced by every little thing that i am dying. the wierdest thing is that everyday around the same time in the afternoon i get what feels like a bad fever and my jaw tightens. i need to know if this is realted or if something else is wrong with me. thanks for your help.

You should let a doctor take a look at you to rule out the possibility for any physical illness. Never test drugs again, not only is it against the law but it is also dangerous. Explore the possibility of resolving your problems with psychotherapy.
