I admit, I am angry over an situation but more confused, but I know anger is there. What I do know, is that it is not worth me blasting forth with words that will cause damage. I do have a heart and I do care. Once words are released, they cannot be taken back.
A gentle answer quiets anger, but a harsh one stirs it up.
Kind words bring life, but cruel words crush your spirit. Proverbs 15.1,4
Is it wrong to be angry or to feel anger? No! It’s normal.
Although the condemnation felt makes you feel bad. Again, normal. I have been taught it was wrong all my life to have such stern feelings to where I am a bad person, unworthy and so on to have such emotion. Anger is a normal, natural emotion in each of us 
If I said I was not feeling anger, that would be a problem. I would be in denial.
As I even write, I could put words of anger that could hurt another but I do not want to do that. Where will that get me? Nowhere but regret doing so. My heart hurts but I know One that knows me better than anybody. I feel the emotions, acknowledge and pray that the Lord will help me through it all. He will.
