I would like some advise please about my kids?

please show some decency and don't hurt me by saying mean things, I am trying to do the right thing. I am very very burnt out. I have been for a long time I guess and I just realize that I made a mistake having children. I can't give them what they need emotionally. I feel very tired all the time and I don't like to be around them anymore. I know they feel it and I know I lam hurting them. I try not to. I don't want to hurt them. I was a good mother for a long time. I gave them alot, all my love, all my money, all the time I could. Now I am really squeezed dry. I can't seem to give anymore. How do I live with them? I know I just can't give them away, that would be even worse for them. But how do I live with them when I can no longer stand it?
