I'd try and stay positive if you can, and maybe running through the pluses of UC help toward that end. However, UC is, in my mind, a lot of crap (physical, emotional collateral to depression/anxiety etc.), and I cannot really put a shine on that turd even with a good wax.
Has UC made me a better person?, lol probably not. I was a pretty good person before UC who ate healthy, exercised a lot, etc. I am a stubborn Taurus the bull, ornery and stubborn to a fault, so not much changes me
