Frozen in overwhelm

I have a very fast growing business and no doubt need to hire help. But I am stuck in overwhelm, I keep having to put out the daily fires then when they are out, I am too exhausted to do anything else . Then the next day, repeat. How do I get out of my loop to find out what I can offload (it seems like not much at the moment) and get out of this daily overwhelmed routine? And I also have my toddler at home all day so it seems impossible to stick to any kind of schedule (thanks covid)
