Staying at home

Hi fellow April mommies! I am finding it incredibly difficult to go back to work. I extended my leave and went back this past week and it's killing me. I don't think I can do this, plus my job is just dangerous and my employer doesn't care about my concerns I have brought forth. I've always worked, my mom worked full time so I don't know much about being a stay at home mommy...are there things I can do from home or ways to make some money at least? Thanks!
