Will we ever be "normal" again?

Trevor cried last night because of the pain. He is starting to question the Enbrel and when/if it will start working. He told me he now thinks he is willing to give up all the fun things he used to be able to do so he is no longer in pain. So sad. :( I tried to help him think of all the things he can do without hurting but I am amazed how that list seems to be getting shorter. Now he says it hurts his back to sit on the wall to fish. Will this ever stop?? It really seems that Trevor has gotten worse. We always said it was because he has been more active but I don't know. We are on week 4 of Enbrel. I am really nervous for school to start!!
