I can only use myself as an example. I was diagnosed with Lupus in 1985. I was seriously ill at the time. However, I was eventually downgraded to mild Lupus. It is now 2008! I have never developed any internal complications with my Lupus. So, it is not set in stone that everyone with Lupus will exponentially get worse, that organ involvement is inevitable or that our lives will be shortened.
So, thinking positive....taking very good care of yourself, taking your medications, making appropriate lifestyle changes, etc. can help you to ensure that you do not have organ involvement and that you are able to life a relatively normal life! There is NOTHING about this disease that is predictable. Each individual's lupus is specific to them and we can only do all that we can to manage our disease and/or to avoid worsening of our symptoms.
Take Heart, Be Brave, Be Informed, Be Your Health Advocate, Fight for your health! We are all here to help you in any way that we can.
Peace and Blessings
Look For The Good and Praise It!
