Sometimes we just feel bad, no matter how well our day went. Sometimes we still feel lost, sad and even jealous and we feel all of this at once, for no apparent reason. But please don't be too hard on yourself - while it is quite easy to control your thoughts, controlling your emotions is a particularly hard thing to do. Sometimes we feel that way and that's okay. Don't beat yourself up or convince yourself that you are failing again because you are absolutely not. You are doing incredibly fine and no bad day, no string of bad phases is ever going to erase your progress. Just allow yourself to feel and be if necessary and take good care.
