Shock after nearly being hit by a car?

[maya D]

Me and my sister were crossing the road and the road looked clear i could see a car coming but it looked kinda far away and was going slowly,so we started to cross the road and i think the car must of sped up as the road was clear and so we quickly crosses and suddenly we saw the car and it screeched to hault. After this we felt to shocked we were shaking, i thought i was going to cry, i can also get panic attacks and think i might have had a small one afterwards. But now i can't stop thinking about it and keep imagining us to get hit and i feel really bad that i said we could cross and caused us to nearly get hit. Has anyone got any advice for me to stop feeling this way, i can't get it out of my head. And will the feeling ever go away and i just feel anxious all the time. Thanks so much
