Paula I think God wants you to start doing for yourself and not to realy on anyone but Him and yourself. I know it's hard for I've been there, but believe me He is the only one that does not turn us away nor forsakes us. As long as you keep feeling sorry for yourself, and want your x or children to do things for you, you will never be free of this course that is holding you back. Built up your faith in God by reading the bible and praying to him in your time of need and sorrow. Allow Him to guide your steps by making Him the cornerstone of your life, and soon you will see things turning around for the better. Believe me God is a present help in time of need and sorrow. God is the best therapy of them all. If you allow Him to help you by communicating with Him and reading His word, He will take away all your depression and make you strong and a self sufficient person so you won't have to annoy anyone for anything you need or have to do. That way you don't have to feel bad when they reject you. It is better to give or do for others than to receive or have to ask for help. Try it for once you'll like it!!! Being a victim is not a pleasant thing to be in, it is better and more joyful to be a survivor with God's help and nobody else's.
Lord help Paula learn to lean on you for all in her life, let her see that doesn't mean for her to sit back complaining doing nothing, or having a pity party, but by taking steps to improve her situation with faith that you will be there helping her all the way. Heal her hurting back and give her strength to do what she has to do to improve her life. Help her keep her job and be able to find a better paying one closer to home. Teach her to learn to be on her own, may she realize she is still a young healthy woman who needs no help from anyone but from you as she walks in faith. I pray this in Jesus name amen.
