Degenerate Back Disc Disease

Hello and thanks for any advice or thoughts you may give. I am 40 year old female with two young boys that was diagnoised 7 years ago with a herniated disc. I had to have it removed as the pain was just too much with a small child to bear with doing everyday things, and I also own a full time business. The herniation came back to the same disc, and I suffered with even more pain. As the years rolled on and the pain got worse, and other symptoms became relivant I was then told I had DDD. My activity level decreased, and I had another child. I am not suffering so badly with everyday chronic pain. I have my MRI's and its apparent its bad. As time has gone on I have developed pain almost all over my body. My feet in the morning hurt so badly,my neck, my left leg, my calfs,my buttock, my left leg, and my back has become unbearble. I was sent for If it werent for my two boys, I dont think I would have the strength to go on. I have just gotten to the point that I cant do anything without being in tears due to the pain/ I have been on narcotics for years, and honestly I dont even feel the relief anymore. I am so depreesed, and have noone to "really" vent too. My husband doesnt understand at all.
I am scheduled for a MAJOR surgury in a few months maybe sooner. I am having my L4 and possible L5 disc rebuilt followed up with tytanium rods. They told me today the DDD has shown up in my neck which explains all the neck pain. I am petrafied, but want the pain to stop NOW...Any advice would be greatly appreciated, or just vent.
