This is nothing that is required now especially more than ever you have overgeared full 210 DPS in early Savage content. No need at all to DPS if you don't want to or feel uncomfortable. If your server's end game population is forcing you, that seems pretty toxic to me.

I would suggest leaving your server and move on to better pastures as not all servers have that kind of end game mentality. You could also conversely tell people that you are newish to healing. Communicate how uncomfortable and inexperienced you are, and if the other healer is good, he will take over the main healer role and solo heal where you are lacking because trust me. I am a scholar and I've solo healed parts where the WHM is apparently supposed to solo heal (A1S first phase including both preys with lower I level than now) so it is not impossible nor is it even challenging if the Scholar is experienced.

Just communicate this more to the group you play with!
