When You are Just Over It

When you have been taking care of someone for a long time because you felt like it was necessary and they never show any appreciation it is draining.  I wish I was the type of person to say well go ahead then, you are on your own.  Still when you feel that said person is not being realistic and there is a younger person involved what should you do.  I know I have gone about this all wrong but it is the only way I knew so I can't beat myself up about it. And yet, I am so over it.
