What do you do when life becomes overwhelming?

What do you do when you feel completely overwhelmed by all the problems in your life?

I typed out a whole message detailing some of my problems, but it was far too personal to share publicly on the internet, and even what I wrote was overwhelming, so I erased it all. I feel ill-equipped to handle the issues I'm facing in life, with my job, with finances, with the house, with my husband, with family and friends, with everything.

It's only been in the last six years that I've become lost and unable to navigate issues, and I don't know how to change it. I'm at a point where it's harder and harder to believe I can make things better.

What do you do when you don't even know where to start because there is so much that has gone wrong?
