Hello jme1234: I'm sorry you're experiencing such difficulty. I have had two major overdoses previously. And there are large gaps in my memory surrounding these events. So I have some idea of what that is like. I was glad to read that you are going to be seeing a therapist. From my perspective, I think this is very important so that you can begin to sort out your feelings about what has happened with you & how you feel about it. Also, I would presume, it will be helpful with regard to any legal difficulties you may be facing.
I think that one important point, in dealing with the situation you're in, is going to be to try not to think too much about the totality of it. It would be easy to become overwhelmed imagining all of the problems that could develop, for example, going to jail, losing your son, and-so-forth. It's important to just take it one positive step at a time. As the saying goes, the longest trip begins with a single step. Also, try not to beat yourself up over what has happened. This would also be easy to do. What is done, is done. And finally, try to accept whatever comes up along the way... with compassion (as it says in my Signature quote below.) I practice a technique that involves allowing thoughts & feelings to arise as they will, smiling to them, breathing into them, & allowing them to fade away at their own pace. Sometimes I will place my hand over my heart as a sign of my lovingkindness & compassion for whatever thoughts arise... good or bad. This can be difficult if the emotions are strong. But it can work. It does work for me.
I send warm thoughts your way with the hope that you will be able to find that center of deep peace that resides within each of us...
