I'm worried about whether I should change jobs, and I can't sleep at night

I got married last year, and my husband will be transferred this spring, so I decided to follow along.
Along with that, I'm worried about whether to change jobs.

The company I'm working for now also has a branch where my husband was transferred, and if I ask my boss, there is a possibility that I will be transferred.
However, although it's not bad at my current job, I work a lot of overtime throughout the year, and I struggle every day to balance housework.
To be honest, I've always wanted to quit.

But when the chance to quit comes, is that really OK? I've been working hard until today, and there's no guarantee that my next job will be better than it is now, so is it really okay to quit? I'm worried about that.
Also, I would like to have children soon, but I'm sure it would be difficult to get maternity leave right after changing jobs. But there's no guarantee that I'll have children soon... so I'm not convinced...

I told my boss once that I wanted to retire, but I couldn't shake off the above concerns, so I had them put it on hold.
Even though I'm a married adult, I'm pathetic, I feel sorry for my boss, and I hate myself like this.

I'm worried and worried about what to do, so I can't sleep at night, and I'm worried in the same way even in my dreams, which is really painful.

How can I make a decision?
I don't know what I should do anymore..
