With your very limited runway I'd get another offer with another employer first. That immediately strengthens your negotiation position with your current employer, even if you have zero intention of taking the offer.

Basically start doing some interviews now. You'll probably have to brush up for those as well, and practice.

> I feel stuck and bored > Working 9-5/Mon-Fri is really draining
