And welcome to the board. We are here to listen.
I want to cry. I want to curl up. I want to be there for my SO, but I'm not always sure how to be "there" for myself. I get warn out and I get tired.
Yep, most of us have been at this point (and visit this place regularly even). So... . first word of advice - Take care of yourself!
There is a saying: Put your own life vest on first. Then help others.
First step is just to take a step back and 'stop making things worse', by disengaging when things start going crazy. Set some boundaries and protect your own sense of person.
Keep your family and friends close. You need them. Use them.
Eat right. Exercise. Get some sleep.
Find at least one thing to go do that clears your mind and gives you peace.
From here you will be able to start picking yourself, dusting yourself off, and deciding what to do next. But first is to recover some yourself.
