H.C.
Oh my, you poor thing, you have been through so much and so has your daughter. I know you don't want pitty but I just want to sympathize with you. There are people that care, even people who don't know you. That's the great thing about mamasource; we are moms, we are people and we care. I am not divorced but I am child of divorce and I am a mother. I feel for you. I feel for your child.
Your child is the most important, period. What ever you need to do to get your lives healthy for her is what needs to be done.
Your ex doesn't sound like a positive influence on your child, I am so sorry to hear that because I know you legally have to let him take her. Can you do anything to change that? Go back to court and have your therapist and her therapist as witnesses. I think a two parent upbringing is best but not when a parent is destructive to the childs well being. Maybe your daughter should not see her dad until he takes parenting classes and/or get his situation under control? Until then can you try talking to him? Letting him know your daughters state and that it's affecting her schooling; is there any lines of communication between you and him. Even if it takes everything in you to try and get along with him its for the best interest of your child.
You are very stressed. That too may be adding to your daughters current state. If daughter see's mom sad, depressed, upset, not working, stressed out, that too will upset her. You are mom and the MOST IMPORTANT person to your child; you being in the condition you are will upset your daughter. Know that you are important and special; and that you are so blessed to have a precious little angle by your side. Your daughter is truly a gift from God and she will be your strength.
See what you can do about your getting your daughter 100%.
Continue going to therapy (you and your daughter).
Be very patient with your daughter, make sure she knows she is loved and # 1.
Get a job (I know the economy is in crisis but keep looking).
Draw support from anyone and everyone whom cares about you. Talk to them. Let them know where you're at and what you need.
I wish you the best with all my heart. Please keep us posted on what happens. Many blessings.
