Wanting to go back to school

I have a bachelors degree and currently work for the state in Michigan. Good pay and benefits . But the work mind numbing and I believe contributes a lot to my depression. I do volunteer already but I’m wanting career that helps people. Any ideas? I’m thinking of getting my MSW but I know there are lots of risks there. I’m trying just to suck it up and be grateful but after six years I’m so over it. No people interaction and no growth. I hardly have to use my brain. It’s killing me .
