I’m deeply afraid of regretting grad school

I’m going to start grad school in the fall to earn my MSW. I put a ton of time and effort into making my decision - introspection, informational interviews, etc etc.

And yet now that it’s getting more and more real, I’m afraid that it’s the wrong decision for me. I’m scared of regretting it.

I see a ton of jobs in social work that interest me, and I also have had a career prior to school, so I could go back to policy if I really hate it.

But it’s such a big decision and I’m just so scared of making the wrong one.

Can anyone relate? It doesn’t feel like a gut feeling, this doubt, but I can’t tell if I’m just pushing through a bunch of red flags.
