There is 19 other jobs you can try out. I am a white mage main; so I understand the pain of changes or no changes. But, it allowed me to try the 3 other healers in higher end content; and it was fun. (and a real growth spurt)
Including you don't even know how its going to feel yet until the patch drops in a few hours. Give it a chance and see if you like it. If you do, great! If not; its not the end of the world. Heck I still ran my happy butt as a clunky white mage through savage and still had fun with its short comings. Practically forced me to never die lulz. Its great.

(I don't know how to cheer you up, but that was my intention.)
