The Universe shows me how people really are and I be like "no they not" and the Universe be like "okay, let me show you again" dummy ......

We are all guilty of this, giving people second chances and allowing things to go over your head, but sometimes it is not worth the energy to try and fix.  This is where your gut feeling will kick in, it will not feel right to continue with trying to assist and continue adjusting.  This is the time to wish them the best and continue with what makes you happy.  It will all fall into place anyway, but it is when we are in the middle of a stressful situation that you think there is no way out.  Realistically, there always is, you've just got to change your perception and point of view.  Its a lot less stressful.
