About a week ago i smoked Weed for the first time in my life. I smoked like a little less than half a blunt and about 4 tbs. of some "CHURCH KUSH" was what is was called. The whole night i had a bad trip and became really nervous while i was high. The whole night i wasn't to sleep since my heart was racing. I finally fell asleep but woke up feeling like horrible and dazed.
It has passed about 10 days and i have strong headaches, loss of appetite, feeling like im in a dream like state, trouble sleeping, and what feels like depression and mood swings. Also i feel lack of doing anything and trouble concentrating.
My question is if this is all normal and will it all go away? How longer will i feel like this? I am 19 about 109lbs. And skinny. I have a high metabolism if it matters. plus, my 4 friends smoked also and they had no effects like me i guess since they smoked before.
please serious answers
