One way to respect yourself is to take the space that you need — to make space. To be in silence long enough to hear what is really going on...in and around you.
After all, it isn’t as much about how much you can take in as it is about the other space you have to create to do something with it.
But, you may have to choose it, intentionally.
Leave your phone some place, rather than take it with you.
Plan and go for a hike.
Stop being productive for a minute or a couple of hours (...a couple of days would be even better for you).
Choose a way to experience some silence.
Unending noise (literal or metaphorical) is not good for you. But, you will have to choose a way to get away from it, otherwise it will just keep you surrounded by it.
You may actually have to relearn how to listen to yourself again, past the usual running tape in your head.
It is a matter of self-respect, as all care is.
And, yes, you do need it.
