It's time to think of others a little bit more than you have been. It's not that you are selfish. It's just that you have been distracted by your own concerns: and you've become oblivious to friends who have been struggling a bit. Reach out to the people in your life with a sweet gesture and let them know how important they are to you. Find out if you can help them with anything. They might be surprised at first, but they will enjoy the attention.
