Hi Sweetie,
I can relate to how youre feeling. I am a nurse, and deal with patients who dont seem to give a hoot if they live or die. Meanwhile Im there putting my sweat and blood into trying to keep them alive and go home sooo exhausted, I wonder why I do it. I think you are a Joan of Ark of sorts, giving your life for the sake of another. Hang in there knowing that what you are doing is a good thing. I can also relate to the inability to tolerate noise. I live in a house with tiled floors, which seems to only magnify the noise. I had a mosquito in the house one day and I swear the sound of its buzzing was compairable to the sound a 7-47 airplane makes. That mosquito is in heaven now. My psych nurse said that sensitivity to noise is normal in our case, and there is not much we can do except take something for anxiety and try to keep the noise to a minimum. Funny though, I dont seem to be sensitive to noise at work, and its like 8 hours of continuous chaos there.
