Cannot get a job

I’m almost 30, I’ve been working consistently since I was 14. Have 8+ years working in service industry positions (server, bartender), in addition to a masters and bachelor degrees - honors, Ivy League degrees in political science and economics fields. I’ve applied to hundreds of jobs and barely gotten interviews. Had a professional help revamp my resume, etc. I have worked for the UN, the county government, and in non-profits. I would go back to non-profits but they pay such low wages it would barely cover basic rent and grocery expenses. My partner works for a non-profit and is already in credit card debt for that reason. Also have too much credit card debt because jobs weren’t calling back. I’m feeling dead inside. Could use any advice.
