I'm sorry that happened
@ziggyandjazzy , that's really scary and I'm glad you weren't badly injured this time. Does your school have any counselors you could maybe chat to about it? I know it sounds excessive but I know after my wreck I realized how many negative car experiences I had had in my life (serious car wrecks, being driven by ludicrously unsafe drivers, etc) that I had never thought about, and I was basically double rattled because I started to dwell on how scary those experiences were all over again. It helped a lot to discuss it with others in a privileged space, and if that's something you're into it may be helpful to you as well.
I'm sorry to hear about your previous serious bike v car accident as well. It's scary to be injured, and to not have it dealt with appropriately on top of it.
Take it easy and take care of yourself. Feel free to reach out when you need to and hugs to you in the meantime
