Robin,
What a great question. I've been thinking about it since yesterday. I've learned the following...
To be more patient with myself. I had to lower my own expectations for myself and begin to hold myself accountable in a different way.
I learned to love more deeply. My onset was very fast and scary. The Drs. had no idea what was wrong with me at the age of 24. I learned to appreciate life more and to live and love life. I was on the more serious side of fun loving before I got Fibro. Now I'm on the more fun loving side of serious If I didn't get Fibro I don't know that my husband and I would have hit it off the way we did and still do. He is a kid at heart and is a daily reminder to me the importance of loving deeply, every aspect of life.
I have learned that depsite my pain and grief the world still goes on around me. Despite everything I'm going through there are other people out there fighting their own battles as well. In addition, to not expect life to slow down just because I can't keep up anymore.
It has taught me to be even more empathetic than I was. My friends are constantly in amazement that despite everything I go through I am the first there for them if needed, the first to remember an important event/date and a constant source of support. I just know how meaningful it is and so I am there to offer it for others.
