Am I "fooling" myself?

As I practice more and more on seeing life as Dukkha, something interesting happens. I feel a greater sense of gratitude and contentment. I am not talking about seeing things as they are directly and non-conceptually, piercing through and seeing emptiness. I am a beginner, stuck in concepts. But the more I interpret my existence in view of impermanence/anicca, suffering/dukkha, and non-self/anattā, the more grateful and content I become. Am I "fooling" myself? Is it just another aspect of Dukkha, like when you are in love and don't see that it's going to end/change?
