I've been applying to jobs for 4 months and haven't gotten anything, is going back to school a better decision?

Hi folks,

I'll try to make this short and sweet. I'm 33, currently located in SoCal, currently have a B.A in Liberal Studies along with several credits from a Master's program in both clinical psychology and industrial/organizational psychology. Up until August 2025, I was employed in the food/beverage industry. I was with one job for almost 8 years and the one prior to that for 5. I have been applying to jobs to everywhere under the sun. Even passed some of the exams for office work from CalJobs, but crickets. This is the longest I've been without a job and it's definitely affecting my mental health. I've been considering that going back to school, even for a certificate or two would help me. What are you thoughts? What could I be doing better?
