SAHM who have gone back to work- I need advice

How did you get back into working? Did you start a business or just apply at a bunch of places? I worked PRN in healthcare- quit at the begging of the year because I was having a mental breakdown every-time I had to work, If you’re in healthcare, you know how exhausting it is. I want to start something completely new but also love what I will be doing. I don’t know where to start, how to go about it. I’ve been applying on indeed to entry level positions with no luck so far.
