Is it worthwhile to quit my job to focus fully on my master's degree?
My master's is currently unfunded, but I have a decent amount in savings and plan to hopefully work a part-time job to offset any loans I may have to take out. My undergrad was in Psychology, and I made the jump to Statistics and CS and the transition has been difficult, but I love it. My current job is unrelated to my field, but it is flexible and is funding my education, which is a huge incentive to stay. However, balancing both graduate school and full-time work is taking a toll on my mental and physical health. I have started having back problems and neck problems from sitting all day at work and sitting all night working on homework. The lack of free-time has also started triggering panic attacks. I've been seeking treatment for these conditions, but it all boils down to stress triggering these issues.
I know if I really buckle down, I can get through the semester, but at what cost? Once I graduate, the types of jobs I can apply for pay a lot more than my current job. I'm feeling stuck because the situation I'm in is one that most would envy, but it's seriously effecting my health.
Should I quit and focus on graduate school full-time at the risk of incurring debt, or should I stay at the risk of degrading health? Any advice, personal experiences, etc. would be extremely helpful.
