Thank you for asking your important question. The fact that your boyfriend tried to hang himself means that there has been something unresolved in him for a while. That kind of drastic action doesn’t spring up overnight.
While I applaud you being so loyal and resilient, I also think it is important to keep developing yourself. What I mean by this is that the heavy use of weed, the heavy use of alcohol, and the suicide attempt are extremely serious issues that you cannot fix. He needs a lot of support and therapy and rehabilitation for him to turn a corner. I realize what I am about to say will sound lame, but I am going to say it anyway because it is the truth. Your boyfriend can’t be your whole life. You may want to have him in your life and be his friend –or even girlfriend, but keeping him sober, drug-free and alive can’t be your mission. When someone is as involved as he is in his issues, people close to them go into orbit around them. Don’t become one of the satellites. Be sure to keep your friends, your goals and dream and your self care at the top of the list.
I higlhy recommend you go to an Alateen meeting They are free and there is sure to be one located in your area. They can help with support as you move through this.
