What do you do when you have nowhere to go?

I know you are not into pills but have you ever tried cannabis? I came from a bad childhood and have severe anxiety. Weed is the only thing that even keeps me thinking straight. Im not high 24/7 by any means but when you get to that point of stressed out where you cant even think straight it is necessary. I know this is probably not the answer you were looking for but it really could help.
