over-doer, over-giver, over-available, over-fixer, over-promiser, and go-to person

Notice your patterns.
If you over-do, over-give, over-function or over-explain, takers see that as an invitation. Not because you are weak. Because you are reliable. Start noticing where you go past your own limits.   Get honest about what drains you. Your time. Your money. Your emotional labor. Your peace. Clarity is power.   You cannot fix everyone. You cannot rescue everyone. You cannot be the emotional first responder for adults who refuse to carry their own weight. Do not keep giving to people who keep taking.  Choose reciprocity.   Invest your best energy in people who pour back, listen well, and honor your space.
