My abilities and money were limited but "you tube" became my site of choice and I took on maintenance projects like a mad woman. Once I accepted the reality that it was up to me alone to take care of the house I made a list of all the repairs and maintenance that had to be done and between the help of Home Depot and Lowe's I felt good about my new skills. Painted every room and closet, fixed a leaking commode, refinished scratched and marred bedroom furniture, rehung several doors, and installed new backsplash in kitchen.
I knew I had to sell the house and could not afford major renovations and it paid off when the house sold. In retrospect, I feel my DH was with me each step of the way. This helped the grieving for me because my mind and body were exhausted at the end of each day. Building confidence that you can make it on your own seems to be common among widow(ers).
