Thinking of switching careers, but feeling guilt

I’m currently a school based mental health clinician who really has loved her job for the past almost two years of working there. I started out as a float (like a substitute) for different schools. Then got my own home school, but that school hated me, and wanted me out. Now I have a new school where everything is wonderful but I’m just…done. I’m so burnt out, and struggle to get up in the mornings. Regardless I love working with kids, as they can be so fun and seeing them grow and progress makes me feel so fulfilled, I just don’t think it’s enough for me to stay with the job anymore.

The main thing is that I need money. I’m about to get a job offer that pays me 20k more. That would save my life but it’s in the marketing realm. I’ve been applying to jobs relentlessly but I don’t know if I’m ready to leave. I hate making decisions.

Anyways, obviously I’m not looking for counseling in a Reddit post. But how would you guys handle this situation? Have you handled something like it before?
