Hi and welcome @notmeinreallife.

You mention wanting to take a break. I don't think a weekend getaway would be unreasonable. How old is your son? Could you leave him with his dad for a few days? Give you some time to yourself?

Also wondering if you have ever talked to a professional about this. A lot of companies now have an Employee Assistance Program where you can have a few free sessions with a counselor. And then they can direct you to a longer term therapist if that's needed.
