Stay active. Try to socialize and spend time outside. Hopefully there are a few people in your life who you can confide honestly in and be yourself around.

If you own your home and plan to stay in it as long as you possibly can, think about modifications that you can do now while you have good physical ability that will let you stay independent as you age (e.g. if you're remodeling a bathroom don't put in a deep tub, put in a shower, install wooden bracing behind the wall at 33" to 36" height so you can install grab bars eventually, or just put them in now, there are decorative ones that match your hardware and don't look like a hospital.)
Switch to low maintenance outdoor things like yard, landscape, decks etc. unless you can pay forever for someone to maintain them. Simple outdoor things like flowers or garden or that stuff, keep doing that, it's good activity and therapeutic. fuck shoveling snow unless you want a back injury. Stay off ladders and the roof. Address slippery or dark areas in the home, or hard to open doors or cabinets. etc. Things you're strong enough to yank open or shut you won't be able to do it forever.
