I'm so sorry that happened.
Please know that you will only drive yourself crazy with the "what if" thoughts or the "if I had only" thoughts. I've had friends kill themselves, and I know from experience that those thoughts are by far the most dangerous thoughts to entertain.

It's not your fault, dear.
