Can suffering be the the path to experience bliss?

Yesterday I was very sad due to a relationship situation. Every time that I go to the gym I spend 15 minutes in the Sauna, in those 15 minutes I used to meditated with a frequency inducer that last 15 minutes. Yesterday I concentrate my all my awareness on the pain that I feel inside with out trying to fought it or explained why i felt that. Just, awareness and in couple of minute I started to feel this immense bliss filling all my senses. I believe that if we use the pain as an object to center our self then we will access to the frequency of love and we would be experiencing bliss. What do you think about it?
