Do a chore? Take a rest. Do a hobby? Fake a rest. Exercise? Long rest. Break up an argument between my kids? Rest. Everything is rest.

I just wanna go, do, finish, whatever.
The serious answer might be meth… honestly OPs post sounds exactly like how my executive dysfunction manifests.
It might be worth looking into a referral to medicate this if you can, OP.
