I am so sorry your friend is a jerk. She problely has no idea what she has done.
I have also had a similar experiance.Years ago I just had had a misscarrige, I was more than just sad.
My best friend said to me "Snap out of it. Get on with your life." I know she ment well, was trying to help in her own way. I never forgave or forgot. That was 5 years ago. She is still my friend. Though I will never tell her a personal problem again.
The moral to this story is never forget who your true friends are.
Good luck. You will find a true & loyal friend if you just look around at who has been there with you no matter what.
