Flipping Tables

If there is such a thing as "sin," are some sins more serious than other sins? How do I get rid of sins that are piling up in the corners of my life, getting out of control, and seriously messing everything up? I really do need to stop smoking. My chest hurts. Drinking a bottle of wine a day can't be very good for my liver. I know, I'll drop off some clothing at the women's shelter! If there really is a God, He will see me doing that and maybe when I die, if there is life after this, He'll remember me doing some good stuff and cut me a break on a technicality. 

Is there any hope for me? Should I care? Should I take another happy pill my doc prescribed for me and just forget about the whole thing? Where is that joint I rolled last night? 

Is anger a sin? I hope not because I am ticked off a lot. I remember Jesus was seen TIPPING TABLES over in the Temple when He got angry, so it must be alright for me to be upset once in a while, too, right?
