If you hold in your feelings, then frustration, resentment and even anger will build up. The only person this affects is you.
If you can’t find a way to tell someone how you feel (in a calm way) because you don’t like conflict or you don’t want to hurt someone’s feelings, you must find another way to let go of what you’re feeling.
Writing can be a very helpful way to do this. You can write a letter to the person (which you won’t send) explaining exactly what happened and how you feel about it. You can then tear up or burn the letter. Or you can simply write in a journal or notebook about it. This helps you release it.
You could also vent your frustrations to a trusted friend, or coach. Someone who is able to listen and let you get it all out without taking it on themselves or adding to what you already feel – they’re there just to listen and let you talk, and perhaps to ask some guiding questions to help you move beyond what has happened.
The important thing is that you must release it or the pressure will build and it will impact every aspect of your life. This is important for everyone – and particularly so for those who are highly sensitive.
