That's a tough one. Yes, people want to help and they probably don't realize that you don't want to talk about it so the only thing to do is tell them you are too upset right now to talk but thanks anyways. I'm sorry that makes you mad and know that you don't want to think about what is upsetting you but you must be showing it in your facial expressions to them that you are upset.
Sorry I'm not really helping. I think I probably shouldn't have even posted as I am down too!!
Hope you feel better soon.
Linda
