Denise 200 words that might have a positive influence on your employment prospects is a good investment. I agree with Jan's thoughts above. You have excellent communication skills and this could be a very good vehicle to highlight and promote not only yourself but the plight of many middle aged people.
You have sacrificed a lot to just maintain your home since becoming unemployed and you have worked very hard to find work, genuine effort and endeavor deserves to be recognized and rewarded.
Hope you go through with this, good luck.
