Am I making a mistake going back to school?

I have been working at help desk role in education for four years. I’m 30. No formal IT education or certs to speak of. But I’ve hit a ceiling. This team has no room for growth. I thought about a total career change but decided that was way too much work and financial steps backwards. I’ve enrolled to do some work at WGU to gain certs and some paperwork and still be able to work full time. However looking at the IT hiring issues in various threads, I wonder if I’m making a mistake.

I suppose it’ll be a few years til I’m done, so maybe the job market will improve by then. I’ll also gain some more skills I can use in my current, albeit with no boost in pay or title. But I can’t help but feel nervous.
