I get that at least once every week...(im recovering from depression) You just have to keep yourself up how ever you can. Weed is the best! Im 17, unemployed, didnt finish highschool cause i got sick (a sickness i might have for the rest of my life) and currently just sitting around smoking weed. So i get those feelings A LOT. Sometimes i have anxiety attacks and not even weed stops it. So its like my only lifeline to get me through has just died... SHIT! where am i? what am i doing with my life? what CAN i do with my life? so i totally understand how you feel. Just remember that when youre thinking negative youre only making it worse. SO STAY POSITIVE!!!! anyway thats all the stories and advice i can give ya for now... I'll send some positive vibes your way... i hope evry thing works out right for you and GOOD LUCK.
