JayPee--I read your post this morning and my heart just breaks for you. My son has said similar things to us, wishing we were dead, wishing he were here so he could slap us, etc. As I read what your son said, I just felt so angry--angry with him. I just want to throw my two cents in and say that I said a little prayer for you and that I echo many of the responses to you. I so totally understand the draw to continue to try to "rescue" and "save" and I'm still dealing with that myself, but I just want to say that I hope you will come to the point that you can value yourself and the life God has gifted you with to not allow yourself to be beaten down. I think, at least for myself, I have misguided and inaccurate patterns of thinking about Josh that continue to lead me into being involved with his drama and with putting up with his abuse, but no one, and I mean NO ONE, deserves to be spoken to that way, least of all parents who have loved and made sacrifices for their child.
When I'm struggling with my heart softening and giving in, I try to remind myself that he is not my "little boy" anymore. He is a grown man, an adult, and I need to look at him that way. Secondly, he is capable of being nice when he wants to, so his abuse is a CHOICE. Third, if I continue to allow it, I help him to continue to do evil and I help reinforce that behavior because he is rewarded for it. And it is evil. God says children are to respect and honor their parents, even the bad ones, and He takes that very seriously.
You (and I, and all of us here) have to take care of ourselves, both physically, mentally, emotionally, and spiritually. God has given us the life we have, and it is a stewardship he has entrusted to us, to use wisely. My husband has reminded me of this at times. That to continue to allow our son to beat me down is to negate the responsibility I have to live in the peace and joy He desires for me to have, which is not only good for me, but gives glory to Him. When I allow the abuse, I live in a state of depression, despair, guilt, fear, etc. and that is not God's will for my life (nor yours). You have been a faithful and loving parent to your son, as have I. That is all we are expected to be. I pray that God will strengthen you and enable you to do what is necessary to live as He wants you to live and what is ultimately best for your son. Don't feel like a failure; we all trip up at times just because we are all loving, compassionate, giving people. If we weren't, we wouldn't be struggling in the first place.
