How do I leave an abusive marriage?

My husband has become every type of abusive except physical. We have three kids under five. I am a stay at home mom and still two years away from graduating with a bachelors. I have no family help. I have told my mother in law and parents how awful he treats and the things he has says to me. They all feel I should suck it up because it will be worse to financially struggle alone. I am scared of how his behavior will affect our kids because yes, I could suck it up, but I’m scared they’re being emotionally damaged along with normalizing this type of behavior. I have been planning to leave after I graduate in two years so that i can provide for my kids. I wont be able to make more than 27,000 on my own if i left now. I have calculated child support to be 1250$ a month after I leave him. Should I wait it out till i get a degree or will the damage already be done? How do i even leave with no money? I hate the thought of taking my kids to shelter. - there is no extra money for me to hide away - i have zero friends - I live in Georgia
