YES whyme. you can go without anyone knowing and in a narcotic anonymous meeting means even the people in NA can't say you were there. i've seen teens at meetings often too. so not to worry bout that, friend.
as for ending up in a mental hospital your drug use would not cause you to go. i think a lot of what makes you feel this way is the weed. but if you could go to therapy a lot of your pain will be addressed. do you think your parents would allow you to go? are you under 18?
also are you feeling so down you feel there's no solution?
thank you for your kind words, whyme. i'm always here to help if i can.
