Sure, but why? What does it gain you? You're certainly not hurting them.

I also don’t have to go at it alone. I’ll have my family affected as well in this scenario. I’ll have their support as well, no?

That's between you and your family. But if you're working on yourself the way you should be, whether you have their support or not shouldn't matter. Though you should also probably be teaching them to do the same thing.
