Tired or hearing we aren’t ready

Looking back on my life I never really wanted children, but things change I guess, I met him in middle school 8 years of love and hate but i guess high school sweethearts don’t always get along. I fell in love with him and we are still together but now we are expecting a baby in October and we are still trying to figure out life. We are extremely happy don’t get me wrong but it’s scary , I’m 20 and he’s 22 he pushes me every day to do better and I’m thankful for him, no we didn’t go to college or get fancy degrees but you can bet your ass we will be the best we can we both have good jobs. I’m just so sick people telling us we aren’t ready or we will be bad parents.
