How do you get through an identity crisis without having your life completely falling apart?

Feeling very depressed atm due to an identity crisis.
I’m a small business owner and things are starting to fall apart. I can’t afford to let that happen.

What actions can I take to change this? I have friends and family but I can’t tell anyone in my life about this. Therapy doesn’t really work. Any suggestions or tips can help with getting through this?
