Tufva was started as I had gotten bored with my original main and I had the bright idea that it would be good for the guild to have another healer (at the time we had 1 or 2). At the time I was terrified of instances, so I'm still not sure how I thought that was a good idea. I must have over-dosed on chocolate or something.
I healed groups a couple of times while levelling, but it was hard work, so if anything it had made my instance phobia even worse. Just the thought of it made my palms sweat!
One day I was chatting with a guildie who was also levelling a healy priest alt. He'd instanced a lot as he was levelling his priest and he introduced me to my first piece of the puzzle of that is healing: healing tactics. The tactic he explained to me was that as a healer you sometimes have to let someone die in order to keep someone else alive. Usually in 5-mans this translates into keeping the tank up at the expense of a DPS (who really shouldn't be taking much damage anyway).
Wow - what an epiphany! This one piece of advice changed the way I healed completely - and the results were great. Not only was my healing much better for it but the feeling of actually having a (albeit small one) clue about what I was doing did wonders for my confidence and made me actually start enjoying the whole instance experience. That little nugget of wisdom was the start of the journey that has taken me from instance-phobic palm-sweating 'oh-shit-what-am-I-doing' to thoroughly enjoying healing my guild's romps through Kara. Knowledge is power - and makes instances great fun!
