I’m having a hard time coping 😕

Almost 2 years ago I made a decision to get pregnant for my older sister who couldn’t have children. We knew from the very beginning, before we were even pregnant, that the child was meant for my sister. Well, she will be a year old on the 30th and I don’t regret my decision. I really and truly don’t. But, a few people have found out what I did and they’ve been nothing but mean and spreading lies. I have two daughters of my own and everyone keeps saying the only reason we gave our third up was because she wasn’t a boy. Which isn’t the case at all. I did something great for someone and in the end I’m getting so much hate for it. That’s literally the only thing that upsets me about it. I just needed to vent. Because I wouldn’t dare tell my sister what’s going on. She’s so happy in her life with her daughter. I don’t want her to feel bad for shit other people are saying to me.
