Hi divine, as if it wasn't/isn't bad enough going through that experience, you must have felt very let down by your parents too at a time you needed their support and reached out to them. I'm really sorry you had to go through all of that
But if we're definately assuming that they/one of them read the e-mail then just make sure you remember it's their failing that they weren't there for you, and that's no judgement on you or the validity of your pain whatsoever.
Thankfully at least you do have your brother and your daughter who do seem understanding and supportive. If your parents aren't able to give emotional support, I'd say to try not to let them add to your pain. Keep your focus instead with your brother and daughter (allow them to be/remain the important people in your life) and with yourself in gradually working through what happened to you with support.
