At the end of the day, as long as you've done all you can do to move forward in a situation, it's been a good day. There's no law stating that you have to fix every problem or solve every puzzle. Don't put that much pressure on yourself right now. After all, no one's expecting miracles. Look back on the past few weeks and take serious note of everything you've accomplished. You just may be surprised at how far you've come in such a short time.
