I believe you have found the right place. Take the advice snodderly has given you as she has been spot on with what she has given you.
This will be a journey for you also and the comments and actions you have told us here resonate with how my sitch started too.
You will no doubt have many questions on this journey and feel free to come here and ask those questions.
This is not for the faint of heart and will put you to the test once again. I am sorry you are going through this but the people here will be able to help you navigate what at first appears to be impossible to navigate. Over time you will be able to see more and will not be completely lost as you stated in your title of this thread.
