I am so sorry that your son is gone, and that he died by suicide. My heart goes out to you.
It is so sad that your son suffered throughout his life, first by the abuse of his father and then by the treatment of his wife. Letting go of negative feelings about people who hurt our children is not easy, and sometimes, it can take a long time to reach a point where the feelings do not control over lives.
I wish you could get your on back, too.
You cannot bring your son back, nor do you want to. He is free now, in a way we can only dream about. What you can do is attempt to intercede on behalf of his child. I pray you have the $ to do this. What happened is not your fault, but you will feel responsible for quite a long time unless you find a very good grief counselor. We all feel responsible, sister, and most of us are not (I can't speak for everyone). May God bless you, enlighten you, and assist you in fulfilling His purpose for you in this life.
I already lost trying to save my son.
I can be involved if I want, for now I choose solitude from hurtful people in my life.
I hope I won't be judged for that.
I need to heal, the pain is debilitating right now.
