As a former college student looking to go back for certifications to attain a good paying medical type job, what are some good options I have?

Ultimately I got a bachelors degree in psychology without getting any certifications.

So, shitty major with shitty options & no certs behind it so i’m stuck & it’s basically like i don’t even have a degree. it’s meaningless.

i’ve seen good paying jobs if you have certs like a BLS or CMA, or even Radiology Tech but just want advice on how I should move as I look to return to school to improve my options & life & well being…
