Am not sure going sorcerer (for any length of time) is tactically a good choice for you to go, given that you already have low HP, and a weak Cha score too.
There are some nice elven gods besides Corellon inthe FR setting ( If that is permissable or your game world) which might turn interesting clerical aspects, besides the classical "medic". But if you want to stay away from cleric-ing, that is role-playing choice to be respected.
You might consider going druid though - given your established focus on nature, who can heal, but, due to being unable to cast cure "spontaenously" is not usually burdened with the job of healing machine. As for variance in roleplaying druids - don't get me started, hehe. And the druidic spell selection fits in pretty nice with a focus on combat, too.
