Have you ever actually tried just healing? I did an experiment a few days ago. I went into dungeons as a SCH, used auto Eos and literally only healed if necessary. I stood around and did nothing for the vast majority of the dungeon. I'm sorry but if you don't DPS as a healer, you are not playing your class correctly at all. It is your job to play to the best of your ability and if you can't really balance healing and doing damage, perhaps DPSing may be more your speed, where you only focus on damage.
