If you don't respect your own energy and sanity...
Nobody else will.
It's one thing to be there for people when they truly need it...
That's important.
It's another thing to become everyone's emotional dumpster.
You aren't anybody's therapist.
It's not your job to be either.
The longer you allow people to "vent" and unload all of their shit on you...
The longer you will keep yourself from improving your own situation.
You only have so much energy.
Never allow others to steal if from you.
Set a boundary and make sure nobody violates it.
You'll drive yourself insane if you don't.
