Number5 I DO understand the emotional turmoil you are experiencing, especially in regards to your dear little grandchild.

Here is something I was thinking about. If a person succeeds in making another person feel worthless, then that person has gained an advantage over you. That person has convinced you that you don't deserve anything better. This person can now, call all the shots and manipulate you. This is what it appears everyone is doing to you. Call your daughter on her bluff by saying, "go ahead, go live with so and so, if you think it will be a better environment for your daughter." Learn to use some of their manipulative tactics, maybe they need a taste of their own medicine, so to speak.
