Has anyone you loved/cared for/been close to just decided to cut you from their life with either no or very little explanation?
Rejection can lead to you having no or very little self esteem. No self respect, little confidence. Feeling hopeless. If you have to reject/cut someone off/exclude someone. At least have the mind to tell them why. Be mindful of their hopefulness that you are soon to squash. I have been rejected many times, it never gets easier.
