I think I may have a drug problem.
Oh no, why do you keep taking drugs when you know how bad they are for you?
I can't help it, they make me feel terrible  but now I'm addicted to them.
You should not be using drugs if they harm you. Drugs could make it so you do not like your life anymore.
I don't know how to stop using drugs, it's too hard.
You should seek help at a treatment center before you problem with drugs gets out of hand. Addiction is very difficult to treat on your own.
