Well I would like to welcome you here
I understand some what I didnt loose anyone when I was young but I sure did all those drugs and more to have a good time and escape. Only it took me till I was almost gone in the ICU and 39 years old. So you are understanding early you need help.
I would highly recommend getting in a in patient rehab to help you learn some tools and ways to live sober. And keep coming here and letting us know how your doing.
Prayers sent your way.
