Think of going outside as an exercise in Survival, from which to return unscathed. (In other words: Don’t fall!)
Here’s where I suggest that you ask your doctor first. And remind you that I am not a medical person or physical therapist, just passing along what works for me. Then with his/her OK, Pass GO and proceed to YouTube to research some exercises for Balance . Keep looking until you find some that you like enough to do on-and-off all day, every day. Try them out. Hold on to the kitchen counter while you practice. I don’t like them either BUT they’re much better than falling down all the time, which gets old quick. Apparently, you have to retrain your body to know its place in space. Not outer space but this space, your space (according to a physical therapist with a channel on YouTube.) What do you think? Is it worth a try? Write back and let me know. Oh, and remember to lift up your feet.
