Listen to beautiful songs like Anni Chhoying, beautiful movies like "A walk to remember', or some beautiful books 'no recommendation', have conversation with beautiful person. These are the moments with spiritual significance. It is not depression. It is the beginning of insight, beginning of realization. It teaches us not get corrupted, not to cheat, not to betray. It tells, "winning is not always the best thing in life". What are the 'values' in our life? May be indulging as I suggested above is not the best thing to do. I'd try not to avoid these important realizations and moments, and to seek answers within myself.
