It’s a bad idea to go to grad school now
- you need to pay off your undergraduate debt first - grad school is completely unaffordable right now
- you don’t have a specific career goal - graduate school should be undertaken with specific goals in mind
- grad schol is more profitable after you’ve worked in a field for 2-5 years
Another huge issue is that you promised your parents you wouldn’t take on more debt. Breach of trust would be egregious, especially considering they co signed loans for your undergraduate degree. You can’t ethically take on more loans before you’ve paid back what your parents took out for you.
Inquire about CityYear. If you have top grades see if you could apply to TFA. Contact your college’s career services. Since you have a degree in community health/health education see if any school district could be hiring for an administrative or even teaching role.
Look into Community Centers: do they offer courses in Spanish (especially Spanish for the health professions) or any other language people speak in your area (Creole, Somali, Hmong, Ukrainian…)
As per s.o upthread, having a course in diabetes communication or smoke cessation helps (through community education or local community college) - this could be a couple hours a week while you work full time.
Your #1 priority should be to find a job that allows you to pay back $500+/month toward your loans (including living very frugally for about 5 years while you work.) You can only consider grad school once your undergrad debt is almost gone.
