Living Life

It is coming up on the two year anniversary of my lung transplant. Since that date I have been trying to live a "normal" life. Working and having fun. Around November I went to Boston for thanksgiving and became a little depressed with my life. We had moved back to Arizona for about nine months.
In AZ I had a good job a nice apartment and we were back with our friends however I started feeling sick. So we had decided to move back to MI.
We have been back in MI since February and have been feeling great besides some small sinus issues.
I have been much happier since the move but at times I feel that I have not been doing my donor proud. Does anybody else feel this way at times?
