Just look at pictures or think on how you looked when you first started to change your ways and compare them with the way you are now. Compare what you experienced back then with what you experienced recently. Also think of the whole process inbetween. This will help you see that you did improve and that this state is just temporary and you're on your way to more improvement.
Note: You have to be on the road to improvement already.
