That is a HUGE step for you to recognize what the whole situation is in your life. You'll hear a lot on this forum about your journey. Yes, this is a journey and each of us have a different path, different turns, and different scenery along the way. But, you can't find that destination unless you really understand the route you're on.
I have been following your posts and felt bad for your struggles.
I am now sooooo glad to see you've found, with the help of DH, what is the root of it all. I think this will be your turn around the right corner to a better journey for you.
I can join you, though I have been 100% OP for the 19 weeks I've been doing the program. I did have my first WI ever when I lost 0 lbs. Not even an tenth. From reading the forum and others experiences, I knew it would come along some day for me. If it had not been for the information and support here, I would have been devastated, crushed, and thousand other depressing words. But, I know it's just another part of the journey. I know this works, if you stick with it. It's a very precise program and there's no room for error.
With that said, I'm so proud you've listened and looked into yourself to find what you've found. I'm sure you can make your 90 day challenge and even more, if needed.
We all love you and will be here to support you.
