Horrible feeling, isn't it?
Bike makers should make pedals to take anything anybody can throw at them, but, um, big girls like us are special.
I don't know your bike, but try riding in smaller (easier) gears. Your knees will thank you, too.
Learn to gear down when coming to a stop, so you start in a less taxing gear. I know, not always possible, but it's a worthy goal. I have no idea how one avoids starting on uphills, road builders (around here, at least) seem to get fiendish pleasure out of making intersections into little lumps, or at the bottom of hills, which is worse.
One last thought. Again, I don't know your bike, or what you have on it, but you might try replacing your current pedals with mountain bike pedals. Now, before they break off. Mountain bikes are built to be take a lot of abuse.
Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
