Finances going into grad school

I’m starting grad school in fall and I’m trying to wrap my head around the financial aspect. I got a TA position which includes a tuition waiver (yayyy!) I will most likely need to get a part time job to be able to cover my car note. I should be able to apply housing to financial aid. What are realistic part time jobs/y’all’s experience working during grad school?

My background is education so I’m not against subbing or seeking a desk job. My friends said that I’m having anxiety about making ends meet but times are indeed tough.
