Legal fee support

I am at the point where to be able to afford legal fees I need help. My ex wife and her endless financial support plus harassment from her parents has landed me in a position that I require help. She left me and disappeared leaving a note on the counter. Her mother and her hid my children from me for over 30 days. I have fought for 2 years now. I have 50/50 conservatorship, I've had to sell my home, exhaust all my resources for over a year and a half. Just over a year after the divorce is over she files another court case and falsified a cps case. I had my sons 47 days of 60 this summer. Long story short my ex is not the person I thought I married and wants to strip me of my kids and take them to live in Michigan with her mommy and new boyfriend . They were born here in Texas and need to remain here and not have a father stripped of his rights and limited to 4 days month. This is humiliating to ask but I can use the help. Anything given I'll be grateful for and I'll do my best over time to repay. You all know I'm not a liar so any help would go a long way.
