The main thing I learned from a difficult period is to listen to my body. Sometimes it's your body's way of saying "if you don't take a break, I'm going to make it impossible for you to continue - to FORCE you to have a break" In those cases there really isn't a quick fix. You have to listen to your body, be extra kind to yourself.

To love yourself you need to be proud of yourself.
To be proud of yourself, you need to become the best version of yourself. Soul, body and mind. You have to prove to yourself that you are “that person”.
