I recommend you to work in part time as long as you continue to go to school. I like to earn money from work that makes the green bucks more thicker in my pocket than SSI/SSDI.
Right now, I am stay-home mom with my children. I have infant that I can't afford daycare, so I get ssi/ssdi.
For instance, California pays you 233 dollars and around 700 dollars from SSDI.
I worked in a company for almost 4 years and I moved to different states in that time. I had to leave my job due to my infant, and I can't afford daycare that costs almost same as apartment rent.
