Maybe you can have a friend or family member help you complete some of the projects. Or you can give some of your clutter away to charity. Or you can take it one step at a time instead of trying to do it all at once.
Have numerous projects around house, inside and outside. I will not complete in my lifetime. I am older. Lots of clutter, don't know where to start. Any suggestions. Leaves me feeling depressed and anxious?
Call AARP, Salvation Army, Goodwill all can send someone to help you.
As I've been recovering from a bad burn and am also older, I just looked up and found a good Handyman ! He does all kinds of different things for a very reasonable price. Something you might think about.
