I'm very happy that you called your MIL. I couldn't imagine that she would turn you away. Now, you have your Plan B in place and can move forward. Now you can a little easier knowing you have someone you can rely on for support and assistance.
You will find that during your journey, yo will learn to ask for help from others. People do not mind helping, if they are asked. I have found that many will wait for you to ask them. When you do, they feel priviledged and honored to assist. So, do not be shy in asking. This is one of the lessons that we learn as we walk the yellow brick road.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
