Anyone else have lack of support?

Shelby
So I'm not quite sure which category this falls under in the communities. But I'm in my mid 20's TTC with my husband and it's amazing the lack of support from people!
Has anyone else experienced this? I feel like people are so negative when someone in their 20's wants to have a kid and only talks about the negatives side of parenthood. 
If I mention TTC to anyone, they always say things like "oh, are you sure you want to do that?" Or "have fun when you're up all night." 
What are good responses to people who say things like this?
