Well, obviously i'm not skilled in any area of this. But i think its important you go 100% on this. Because when you do, they can help you, and thats all they want to do and what they are there for.
If you keep it in, there isn't anything to do, or help you. But if you tell the truth, they will do what they can to help.
I had a friend with something more milder than this, and as long as you make sure you control yourself and stay strong, things will improve and get better in your situation.
I hope that helped a little if at all. Stay strong and good luck
