Need Help Scared of jail and hell

I am addicted to petty shoplifting! Having been arrested more than six times, I am ashamed to admit I do not know why or what triggers it. I know it torments me to think of the ones I hurt including myself. I do not have a drug problem normally that's always the reasoning. That is so untrue in my case. I believe I suffer from mental problems and never diagnosed. I feel I deserve rehabilitation just the same as an addict because shoplifting is an addiction.I wouldn't get help in jail only punishment and seclusion from my family. I at least should get the opportunity to get help and if I dont take the help then I am given the harsh punishment of confinment in jail.
