Just because you aren't given the credit and haven't been recognised for your work doesn't mean you have to give up or stop. You don't always need credit, other people do not always have to know what you are capable of doing as long as you do.
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.
