Hi Kris, a whole year without SI? Wow, that is absolutely awesome!! Congratulations on reaching a wonderful goal. Be very proud of yourself for that. Hugs to you for your hard work and for succeeding.
As far as the depression goes, I know what you mean. Ive been in a deep depression for a couple of weeks. The holidays were very hard this year. But I managed to get all the shopping, cooking, wrapping, decorating, etc. done all by myself as my kids are grown and out on their own, and my husband was travelling for business. Maybe this would work for you for your house.
Make a list of exactly what it is you want to get done, and every day promise yourself you will make the supreme effort to do just that one thing,and then do it. That's all you have to do, just that one thing. The rest of the day you can do what you want. Eventually, the week will be over, and all the chores will be done. I know it sounds simplistic, but it worked for me. And it really helped my depression a lot that on Christmas day when my kids came over that I was ready for them.
Try not to be too hard on yourself - do what you can. Take care.
