Hey man, I agree you're stuck in a rut, but I don't think its the cannabis to blame. I can't tell how old you are, but if you live with your parents probably not that old (unless you're post-college grad living in their basement, in that case sorry ). Anyway, I always feel guilty smoking near my parents and they even know I do it. Once I get out of the house (I go to college and live with 5 roommates, four of which smoke), all that anxiety is gone.
I can't say I smoke alone very often though. I'm surprised you don't have any friends who do it. After five years as a smoker, I've learned to think of the practice as less of an addiction and more of a life choice. Its a spliff after work to wind down or to enjoy music more. Its not like you're shooting up and passing out for a few hours. Of course, the choice is always yours. I'd recommend you find some stoner friends, though. They're the best! :thumbsup:
