It isn't fair when you know a simple thought from them could rearrange you. All that remains is the hope that somewhere along the way you discarded a stronger more vivacious version of yourself. A fragment to be called upon when you have nothing left.
Living a life like this drains you. Feeling so alone even when you are with someone. I would rather be alone then lonely with someone else that make you feel lonely. You should never feel that way a relationship.
