What's a good way to go about finding a therapist to help with post-traumatic stress disorder?

Back in June, I had a very traumatic car accident in which I ended up flipping (as in “ass-over-tea-kettle”) my car into a ditch. I was not driving recklessly, it was entirely the road and my car not being suited for the conditions. Luckily, I walked away with only a small cut on my finger and spine/neck compression. I am still dealing with the residual feelings from this accident, being my first motor vehicle accident and that I was also traveling alone. (Luckily I found my cell phone and my boyfriend was only minutes away, he is my hero)

So anyways, I have been recommended to see a therapist to help put these feelings to rest. However, my doctor said that a therapist is a very personal choice in that everyone is different so she felt that searching for myself was the best solution… but how?

I have no idea how to tackle this problem, even a place to start would be a huge help to me.

Thanks to everyone in advance for your help and advice! Any contribution and help will be greatly apprecited ^_^
