I need to vent! Sorry

Okay so I suffer from PCOS and Infertility issues and have been trying to get pregnant for over a year now.

Why do people have the need to tell me that they "can just have my baby" or "borrow my kids you won't want one after"... Or "your so lucky I wish I would have never have to worry about getting pregnant or dealing with a period"

Do people not understand how much that hurts to hear? Am I just overreacting?
