Then you're doing something wrong.. Try a different area perhaps? SH is one of the easiest classes to level, with Vamp claw and CLD you shouldn't have problems at your level at all.
do not CDL if you dont have live support in duo or great skill.
do not nuke groups if you dont have live support in duo or great skill.
choose mobs that are 1-2 shot. 3 shot is not good.
choose mobs that are weak to mattack/wind/dark (e.g. angels in VoS).
maximize your casting speed (acumen in weapon / proper robe set / +wit dyes / m.haste potions / blessed shots / buffs) so the mob will never ever come close to you.
do not hit social mobs gathered in close group, rather wait a bit until they spread around.
have wampiric claw(could save life and both deal dmg) / healing potions / life elixirs / bsoe ready to use.
Yeah, seriously, you should not be dying that much unless you are CDL'ing. With the exception of a pvp fight here and there, I can MANY lvls without dying.
Also, it probably is not needed but I'll say it, don't forget to kite a mob if you need to.
