During my past visits and calls to your staff, I know I have not been the most pleasant person. I try vehemently to be polite and pleasant, but my extreme pain precludes such actions to a significant extent. However, I would like very much for you and your staff to know how much I appreciate all their efforts on my behalf, and realize the difficulties with the seemingly endless and fruitless process of working with my insurance and the time it is taking to have my necessary surgery approved. I am writing this letter to THANK all your excellent staff and particularly Lauren, who works tirelessly on my behalf. Once again, please excuse any seemingly lack of thankfulness to my current condition (and know that this is assuredly not the case). Please know that I am ever thankful for all your efforts!
