Get active daily and if nothing else, the endorphins will help you feel better and more positive. Getting old sucks the big one. I think a lot of people feel the way you do to some extent. When you reach that age where parents and other family members start dropping it's natural to start doing the math on your own mortality. It's rough, especially if you are a glass half empty kind of person like me
You can take some solace in the fact that we're all "living" in a simulation anyway...that's what the nerds say at least.
Good Luck.
