I’m not lazy

I’m 22 and have a 2 month old. My parents talked me into moving back in with them so I can finish college. My siblings and friends always complain about how lazy I am and how I’m at home all the time and never do anything. I help out with chores as much as I can but I’m taking 18 hours of science courses online so there’s only so much I can do. My mom always acts like it’s such a burden for her to watch my son when I go to work three nights a week even though she volunteered. She’s currently trying to convince me to stay with them until he’s in kindergarten so it’s not that they want me to move out. It’s just getting irritating listening to my friends and siblings bitch about how lazy I am and how I don’t ever have to do anything.
