Hi aureatedawn, and WELCOME to BPDR!!
Fear can be paralyzing, but it helps me to remember that inaction is a choice too. Also, I know what I get from things staying the way they are (usually not what I really want), so choosing to face my fear and find a new way can be better than just living the way I was. It's really better on the other side of all this, though I know how much work it takes to get there. You can do it.
There is a tool section on your upper left screen that can help you with your thoughts and emotions. I really strongly recommend them, especially twisted thinking (and untwisting!), the four agreements and separation of stuff. I hope you find them as useful as I have. If you need help implementing them, there are separate forums for each tool where you can get feedback and help.
I'm glad you have found us. It sounds like you have been through a lot recently and I believe BPDR can help. Welcome!
