Your FEELINGS do not HURT other people.

It is not necessary to protect other people from your FEELINGS.
Your feelings are NOT 'bad' or 'wrong'.

There are, almost certainly, more and less EFFECTIVE ways to EXPRESS what you're feeling, in order to get your NEEDS met.

The fact that
THEY DON’T WANT TO LISTEN TO or HEAR
what you want to say
doesn’t mean that
WHAT YOU HAVE TO SAY is WRONG or BAD.

So, here's where the anger comes in: You feel SILENCED by people who try to shut you down. You experience BEING SILENCED as being expected to hide, or otherwise NEGATE an essential part of YOU. You don't want to have to be SILENT about what you feel, think or need any more than you want to CUT OFF AN ARM OR LEG.

The ANGER tells you that a BOUNDARY HAS BEEN VIOLATED.

The way to USE the anger is to INSIST that people RESPECT and LISTEN TO your needs and feelings.

People who DO NOT RESPECT YOUR NEEDS AND FEELINGS are NOT friends, and they do NOT love or care about you, REGARDLESS of what they may say to the contrary. Because they're busy protecting their SELF IMAGE, not their relationship with YOU.
