White Mage is the most difficult healer in PvP, and since you're just starting out, I might recommend switching to Astrologian or even Scholar to get your feet wet.
I found AST to be more difficult to heal. The shields are weak in PvP, Aspected Benefic is instant but only 120 potency shield and drains MP fast, they may keep themselves alive while sprinting but AOE or multitarget healing is AST's weak side. AST has only stun on long cooldown and Blizzard 2, while WHM has stun, sleep and B2/Fluid Aura. WHM's regens are stronger and there are 3 of them and they all stack. WHM also has more MP restore options with Assize. So it comes down to Lightspeed vs Sacred Prism, both of which are great.
SCHs rely on AF stacks to heal bursts, and it's hard to manage a limited number of them for a new player. MP is also a problem as Adlos are very MP consuming, and Physick is often not enough, so SCHs often die mid match without MP.
