i dont see anything wrong with what you tried to do with changing your faucet. i personally dont think its a good idea just to accept that you cant do something. you have to test your limits sometimes to see what they are. as long as its not something dangerous which could get you seriously injured i dont see the harm in trying. in this case you would have had to get a plumber to your house if you didnt try anyway. i think one of the main things we have to do for ourselves is not to be too hard on ourselves and the mistakes we make living with this illness. im still working on that right now for something im angry with myself for letting happen that did cause a serious physical injury. sometimes we are our own harshest critics.
