Look on USAjobs.gov for positions at FDA or as support staff at NIH or similar. A BS BioChem should be employable, but you need to look in the right places.

Go back to your college for a few days and make appointments to meet with people- go to career center, advisor, professors, etc. have career center walk you through steps to get you on handshake, LinkedIn, etc. have them review your resume. Usually there’s a list of alumni in your field you can contact to network.
Congrats on your degree
