The gods envy us. They envy us because we’re mortal, because any moment may be our last. Everything is more beautiful because we’re doomed. You will never be lovelier than you are now. We will never be here again.
Be kind to yourself. Stop telling yourself that whatever you are struggling with “should” be easy. If something is hard for you, it is hard for you. There are probably Reasons, though those may just be how you are wired. Acknowledge these things. When you finish something hard, be proud! Celebrate a little.
And really, just stop saying “should” to yourself about your thoughts and feelings in any context. You feel how you feel. The things in your head are the things in your head. You can’t change either directly through sheer force of will. You can only change what you do. Stop beating yourself up for who and what you are right now–it isn’t productive. Focus on moving forward.
