Oh Cheryl - I know it is so hard to keep your cool when all the "what ifs" start assaulting your mind. It really takes a lot of effort to keep the negative thoughts away. Try to think of all the good things that could happen or that already have happened like the clear Chest CT and the MRI clear. Push the negative out and replace with nice happy things. When those thoughts come, accept them, but give them a very short time limit like 3 minutes or less, then go to a happy or funny thought. What helped me was doing something physical, even if it was forcing myself to vacuum at 3am, or doing toe touches, or whatever you like to do - maybe eat chocolate, take a relaxing bath, read, etc. Is it at all possible to move up the surgery date so you don't have to wait so long? Maybe if you can express your anxiety to the doctor or have someone call for you, they might move it up or at least give you something to help calm the nerves. It couldn't hurt to at least ask. Hope things go easier for you. Keep us updated. I'll be sending positive vibes your way.
