I didn't catch in your stich you spoke to a DB coach. If Jody told you not to contact your H then you need to listen to her.
I can tell you how to GAL. There are so many different ways, but it's important to start with at least one. Try walking a mile everyday. Take a stroll around the neighborhood and appreciate the beauty of nature. Go to the library and take out an exercising video to get in shape. Start a personal journal and fill it with the negative thoughts you have. Then go back and rewrite your sentences with positive thoughts. Example: Negative thought: I can't do anything without my H. I need him in my life. Positive thought: I took care of the pool the best I can without H's help. I can do things without him. If H wants me in his life, well then he know where I am.
Also in this journal write a list of things you can do to GAL. Fishing, walking, running, take up a craft, volunteer. There out there you need to find them.
I know your hurting and I feel bad about your stich. All I can do is give advice; good and bad. Fixer
