Hi Kirsten, glad to see you posting again. I was wondering where you disappeared to. You mentioned mold, well mold is mold but have it checked and find out if it's black mold. If it is black mold you should make sure you get every trace of it out from behind your wall as this might be a big part of your health problems, it can even cause some neuro problems. In any case a new bathroom sounds like that will be cheery once it's done.
Sorry you're so lonely, don't forget you still have that good friend,,,your camera....those pictures you post are just awesome. Some magazine or art gallery will pick up on them if you're persistent.
Hope you start feeling better soon, your kitties are always there for you as well as PT.
