What I would offer to you is this piece of advice.

First, don't rush to start a business. When you are "tired" after having been in a certain job or certain industry or anything actually, the first thing to do is to take a break.

You can't be objective or clear right after you exit something that has drained you.

Second, I respect that you have a family and responsibilities. There are folks who depend on you. Perhaps you can negotiate with your family a timeframe where you can hit the pause button and reset. This way, it'll give both of you what you need: It'll give them reassurance and it'll give you a break.

In sum, I don't know why it works this way, but there is something magical about paying attention to yourself and giving your body, mind and spirit what it needs. It somehow creates a space for the next step to reveal itself. And because you will have gotten all the "stuff" from your industry out of you, you'll create a clear line for the right something different to present itself.

I wish you the best!
