When Could We Say to Ourself that Enough is Enough?

I have began saying it a lot lately because I am sick of putting up with people's BS. I have put up with people's baggage for so long, that I have decided not to put up with it anymore. I have been a scapegoat, I person who takes abuse from people and puts up with it, but as of January of this year, I stop doing that because I had just had it with people who think that they can take advantage of me and rip me apart, so I have begun to stand up to people who think that they can treat me like trash.
