Legit work from home

Hi I am trying to find a legit work from home job that doesn't require selling as I am not a people person and that's just not my thing, I also have nothing beyond a high school diploma. I am a stay at home mom to a 2 yr old and twin 8 month olds, their dad works away so he's gone for weeks at a time, although he makes good money he barely supports me and doesn't leave money when he goes, he won't let me put them in day-care so that I can work outside the home I want to work so I have money to get things I need and want, I'm getting tired of going without necessities and cutting bottles open to get every drop of something out bc I don't have more and don't know when I can get it. Is there any work from home jobs that are not scams, I also have no money for start up. I live in Pennsylvania. Any help would be appreciated as I don't even know where to start looking I have googled but can't find anything that isnt a scam.
