How to stay positive?

During the day I kept thinking to myself how do I stay positive during this diet? I am miserable! I am still transitioning and it's horrible. I while be driving just thinking about the horrible rash and I how unhappy I am, and why am I the one who has this candida illness. So there will be bad days, and I wonder if the bad days will outnumber the good days. I think to myself I am doing this so if I have a child, my child will be healthy, and that has become my motivation. I think I need to make a list of all the positive things that will come from this and carry that with me and look at it when I'm having a hard time.
