Jeff....
I know what you mean by not letting them wear you down....I went through this for 10 months (7 months with an attorney) before I was successful in getting a modification. It was a rollercoaster ride to say the least and each and every day I went through a myriad of emotions from happiness to sadness to fear to anger to shear frustration....and this was almost everyday. So, be prepared for the fight of your life....even though you hired an attorney, it still rocks your world on a daily basis because this is YOUR home we're talking about! Be sure to stay in constant contact with your attorney....I e-mailed mine like once a week for a status update. You have to stay on them to to get them to do what needs to be done....it's like anything else, you have to make sure you manage it so it gets done right.
Good luck, I am praying for your success. God bless you and your family. Keep us posted on your progress, I'll be following with great interest.
