Can I not fall when I walk to the bus stop to go to school?
Why aren't you worried about falling down?
It's not hard to not fall down or pick up your feet again.
It's good that you're able to maintain your balance. If you are falling during mild physical activities, you should consult a medical professional.
I'm tired of being treated as a invalid. I wasn't injured.
That's fine and I agree with you, just because you struggled a little doesn't mean that you can't walk. You just need to work on keeping your balance and then everything will be fine, maybe do some yoga or something to help with not falling over while you walk?
