It doesn't necessarily take Christ, but anything that can give you hope and lead to a positive attitude will naturally help you with anything :D Like this very answer (Suffice to say, I'm not Christ :S) !!
Feeling sorry for yourself is a very english thing to do haha it's in our culture, but sometimes I feel like we should take the American view and just be happy no matter what :)
Best of luck with whatever needs turning in your life :)
If it's already a good life then I wouldn't turn it around by the way, just saying ;)
