Angel - I am sorry that you had such a traumatic experience. I can only relate a little because I was bitten by a cockier spaniel when I was a little kid and it took me many years to get over my fear of dogs. Even now I am wary of dogs I don't know especially pit bulls. The great thing is we have a dog which I love and it provides so much joy in our lives. I hope and pray that you will eventually recover also from your experience.
On April 22, 2017 I was Attacked (Mauled) by a Pit Bull and I had to get stitches and I have Severe nerve damage and my wrist hurts ALL THE TIME When the weather changes or when I bump it on something or when I write too much. I have Cynophobia (Mostly Around Pit Bulls), and PTSD.
