I'm so sorry you're having a bad day. You don't need to justify the tears and sadness- of course you're feeling bad. You made a commitment and are a loving and warm person. Your sadness is a testament to the commitment you have to your M.
Although it may not seem like it right now, you will get through this and the sadness will gradually subside. Take a deep breath, and when you feel a bit better why don't we work a bit on some goals? It's such a great feeling when you get the baby steps you're looking for (and you're going to get lots of them). And a great first step to DBing.
Re. the house sale, whereabouts do you live? Getting a sale could take a while, given the way the market is.....lots of time to DB.
I'm thinking of you and we're all here for you. Keep posting and come here to vent.
(((((hugs)))) sweetie

Walk on, walk on, with hope in your heart. And you'll never walk alone.
