Every day? Yikes! That's a lot, especially given that it is interfering with her seeking out normal activities. Personally, I wouldn't tolerate someone getting high on an every day basis, although I don't really object to occassional use (I don't smoke, though). This is a matter of me choosing the lifestyle I want.
It sounds like you are outgrowing her, which is very normal for your age. You will soon have to decide whether or not she is going to be compatible with the lifestyle you want, and act accordingly. You might warn her in advance that this is bothering you, but quite honestly, I doubt she will care.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
