About two weeks from now will mark 7 years since I lost my father, and I witnessed the struggle you are currently going through in my mother. The best advice I can give you right now is to try your hardest to remain positive and reach out to those around you for help. I promise you that this will only make you stronger as time moves on.
My mom decided to sell the house we were living in. It was about 2,400 sq ft on a 92 acre farm, and my dad was the only caretaker of this property which was essentially a full time job. There was no way my mom would be able to manage that large of a property so she made the decision to sell it and move to a smaller property closer to her family. We all learned the importance of having family around to support us through all of it, and you should find people in your own life that can serve that purpose.
The most important thing you can do right now is to be patient and avoid rushing your decision. It took well over a year before my mom was capable of dealing with that kind of decision and she was lucky enough to find a friend that was willing to purchase the farm, taking the stress of putting it on the market off her shoulders. It seems that you have found a great way of dealing with such a devastating situation, and doing improvements around the house will go a long way to take your mind off what you are going through.
It's no easy task recovering from a loss like this, but like I said, if you keep your head up everything is certain to get better.
