WHM has very potent healing capabilities. Divine Seal makes regen very powerful, allowing you to sit back and recover MP. DS also makes Cure 1 heal nearly as much as an unbuffed Cure 2, allowing you to save MP by not casting Cure 2. DS is also on a 60 second cooldown so do not hesitate on using it.

As you play more, you will learn the boss fights and be able to predict incoming damage, incoming spike damage and get better at MP management.

Don't take it all on yourself as well. Your MP management is also due to how well the other group member perform. If you're having to waste MP raising or healing unnecessary damage taken, that's not your fault. Being you're still in mid-level content, I would not be surprised if you're playing with new players also getting used to their jobs and boss fights.
