I Have A Stealing Problem !!! Plz Help ! Or Give Me Tips.?

So it all started about 2 yrs ago( im 13 now) and i use to steal magazines from kroger and some pens or something, and lip gloss at walgreens. Now i've gotten to the point where i stole jewelry from my bff, from my aunt i've stolen : 14-16 bottles of nail polish, TONS of makeup, un-opened deodorant, perfume, un-opened razors, personal electric shavers, electric manicure set, pens, face wash, body wash, jewelry, and some other stuff. I got ALL this stuff while my aunt( shes 18 ) went to work and i was in her room pretending to watch a movie. I also stole*yesterday* from my sisters house( shes 15 and lives with her real dad ) i stole while every1 was asleep. It gives me such a rush! I stole make-up from her rich prissy step mom, a makeup box, and some other little stuff. I wouldn't steal from my sister though. I don't really wanna stop stealing cuz im sneaky and my family is kinda poor so i would NEVER buy all this stuff. I still occasionally steal from stores. Either tell me how serious my problem is, what i should do, if i should stop, will i get caught. If u wanna help me, tell me: some good techniques, what to steal, what stores, how to get away with it, etc.... Thanks!
