Do you have midlife crisis?

How many of us been through a midlife crisis? What did it feel like and how you get out of it? I’m half way through 30s and suddenly started to feel I don’t want to do anything. No inspiration/motivation for work, couldn’t try to finish my master degree all while knowing I should not be in this state. Can’t seem to be able to get out of it. Procrastinating a lot more and spending more than I earn… In fact I became unemployed since December but haven’t got the bravery/intention to go out and find work? What exactly is happening?

Edit: Thanks guys I guess the root of the problem is depression and burnout. I'll work it down one step at a time from now on.
