Why is it that I'm still traumatized?

I had an accident a couple of months back, think it was the 1st of February. I went out at one in the morning to pick my dad from the airport and it was raining heavily. I lost control and the car just started drifting until it hit the palm tree. The accident didn’t look that serious but the impact was quite strong.

Ambulance took me to the hospital and I had a couple of bruises. I thought I was okay until I started dreaming about it on a daily basis. It’s so annoying and I can’t seem to stop the flashbacks. I really don’t know what to do. On top of all that, I still feel sad because I’m still attached to my car (which got totaled). I know the car is something materialistic but that’s just the way I feel.

Time passed and while I’m still not very talkative about it, I still feel it is imperative that I get some advice.

Some pictures of the accident that I posted way back.
