Yes. Even if they are crap. Fight. The world may never be on your side, but dont let yourself be like others. I know i have days where i even seem to be against me. But i know if i cant be on my side, who else will.
Some days are harder than others. But they are YOUR days. Dont take them away from yourself. I recently stayed beside a loved one during her hardest moments. She informed me that her biggest mistake would have been to quit, and she was thankful that she didnt. Be well. Be focused on yourself. But most importantly, be.
