I think it's important to be transparent, but also not to be single minded. I am not defined by my illness so when that is all someone wants to talk to me about, I see that as very short-sighted. We all have burdens to bear, but I like to focus more on the overcoming part of life.
When we talk about our burdens too much, our focus is more on ourselves and our limits. When we talk about our blessings, we show others the power, faithfulness and limitlessness of God in our lives. Our attitude and gratitude is the difference in defining anything as a blessing or a burden.
Yes, our struggles are a part of our stories but God gives us a new song to sing. A bad day doesn't mean you have a bad life. God grants new mercies everyday. 'There are no rainbows without the rain.'
