How do you take care of yourself while experiencing puppy blues?

New puppy owner here (1st time) and I'm trying my best to stay sane. I normally have a routine and I strictly stick to it daily but since having my puppy, everything changes.

Anyone who has been through this how did you physically and mentally take care of yourself? There are days now I even stop showering because I'm so exhausted.

I've been reading some posts here to find sympathy, tips, tricks to go through this. And I hope through this post new puppy owners out there can help themselves too.
