Kathy,
When my oldest daughter was going through a rough time and hurting herself (by cutting) and talking about killing herself, I felt, too, like it was a public indictment of my mothering skills. After all, I was her mother, I lived with her, I took care of her and I felt like her mental and emotional issues at that moment were my fault because I should have been good enough, strong enough...SOMETHING enough to help her and to stop it. I was her mother, for piss sake, and I couldn't find a way to make it all better! That's part of our job as mothers...protecting and making it better for our children.
It took me years (and going through my traumas) to understand that it wasn't my fault that she went through this. It was combination of circumstances, her mental state, her age, and her maturity level to all contributed to what happened. Her father and I put her in therapy, we helped and supported her. Basically we did everything we could think of. But what took me the longest to understand is that there comes a point when, although they are still our children, they are not children and we cannot protect them like when they were little. All we can do is be there, love, support and hope that that's enough. It comes down to their choices, not ours anymore.
Kathy, I read what you're saying and I hear the same words and thoughts that I used to beat myself up for not being enough to make it right, make it better. I also understand that incredible anger and rage for our children taking the life that we gave them and treating it with such disregard.
It's so tough not to take the fears from one child and transfer them to another. Or to another family member. All of what we went through with my daughter happened in the same time frame that I lost my father and sister. I was scared for anyone I loved to be out of my sight. Unfortunately it lead to a lot of resentment from other loved ones when I would bawl them out for being later than expected or didn't get a call, etc. I've learned that explaining why I was afraid to let anyone go helped the rest of my loved ones to understand why I reacted like I did.
Keep talking, keep writing. It does help to get it out of yourself and to stop the fear from becoming bigger by keeping it to yourself.
Hugs
