Grad students- how do you make money? Side hustles?

Starting my master's in May. I'd love to hear from students of all disciplines how they make money while in grad school. Especially those who didn't get funding. How do you get by? What jobs click well with your class schedule? What do you recommend?

Apologies if this is too broad. I'm freaking out about my finances right now lol. Waiting to hear back about my funding application, but even then, it wouldn't kick in until august. I have no idea how I'm going to make money or eat this summer. I barely have enough to move, and I have to move unless I want a 2hr commute
