Perhaps, at some time, someone had mistreated you... more than likely it happened because they were feeling miserable about themselves, also.
Now, it is obvious that you have contracted their dis-ease... it is now yours… The conflict is within you… and, you are now eating yourself…
Chances are you may give this dis-ease to someone else… blaming others is indicative of this very possibility.
This is how dis-eases are really passed on from person to person… one person infecting another… from generation to generation… This is how one person’s problem can become a world problem.
Becoming responsible for oneself will prevent this from happening… of passing on your disease to someone else... so, the next thing is that you will have to want to do is to take on the responsibility for the situation that you are finding yourself in…
