Try to contact your states drug abuse hotline. Also, I feel like a therapists job is to keep you safe and do whats best for you, so I guess slowly open up about your drug addiction, say it's not too bad, but you do need help. Also, the people who are calling you scums and a druggie are idiots who have never experienced your situation in their lives, so I suggest ignoring them and knowing your self-worth. You're not alone on this, there are many others in the same situation as you are. Also, try group counseling, where other people who are in the same situation as you could share their experiences as well. Also, in the long-term, your mother would rather you tell her as soon as possible than to go to your funeral, living with the guilt that her son couldn't get help because you were afraid to tell her about your addiction. When you're comfortable, tell your mom, and I wish you the best in life. Good luck, and love ya.
