We all have (or have had) moments in our lives that haven't been pleasant. Stressful times, painful times, hard times, etc. During these times our mind has the tendency to "run amuck." It's very easy to get frustrated with ourselves and think, "What's wrong with me?" The answer is, "Nothing is wrong with you." Emotions were given to you to use - and using them (although sometimes we wish we didn't) happens. Be kind to yourself when you are having an experience you don't desire.
