I hate myself because I'm addicted and I need to change myself, I have to tell someone the truth about it.
Why do you think that you are addicted?
I can't cut off my addiction by myself because my passion is too strong for drugs
You admitted your addiction, which is the first step to recovery. Join a help group or check into a drug rehab, they will help you get out of that predicament. Otherwise things may continue to get worse for you.
But I don't have time to go to rehab.
There's always a good reason to not do something, but doing it will make your life a whole lot better. It'll make you feel so much better to finally achieve the help that you seem to really want.
