Everybody has said everything I was going to say.
You can't change a lifetime of getting advanced degrees in codependency in just a few days. You didn't get this way overnight, you won't fix it overnight.
Here's what you CAN do, besides letting yourself off the hook you're wriggling on: Pick one thing, and try to do it slightly differently next time.
Like, tell your dad that you'd love to have him stay but this whole thing has you absolutely exhausted, and make a date to have coffee on another day.
Like, postpone talking to your mom until you're home with your bunny slippers on.
Pick whichever one bugs you the MOST that you did, and maybe start there.
There's a coach who has that as his philosophy: just try doing one thing different. And when you feel strong with that one thing, maybe pick another.
He says you start to get a feel of accomplishment faster that way than trying to do fifty things slightly better each day!
Hang in there girl
