Family/friends/strangers calling me insane for having 4 kids?!?

Well it's difficult to keep people's mouth since gossip and criticism rules people's mouth. But, you are happy with your life and your kids why stress over this. Look I'm thirty, alone, no friends (literally), no love and people are constantly asking me "When are you getting married, why don't you have a boyfriend, why don't you have kids?" I mean people can be very cruel and pain in the neck I know but don't waste precious time on stupid people. Be direct and tell them I'm happy with my life and God has provided all of these beautiful gifts cause he knows I can handle them and deserve them.
