Hi, Iggy - I think this is a very common side-trip on the journey to becoming a cyclist, so don't sweat it, there's nothing wrong with you! I had a nasty fall early in my road-biking and dealt with a lot of fear. It WILL pass. I went back to my hybrid for a bit, then one morning in the garage, I knew I was ready for the road bike - with platforms. Some time later, as I got dressed, I felt ready to reach for my bike shoes again and pulled the platform pedals off. I read a quote somewhere from G. Terry herself about how many new cyclists ruin it for themselves by rushing things. so -

Eassssy does it.

ps, I always rode away from the house and practiced stuff like unclipping on a back road. Way back road.

Good luck!
