Don't know what you've tried so far, so here's some general ideas. Hope I'm not repeating anything too obvious.
Have you been keeping your armor stat and weapons up to date? With just store-bought equipment from Lannegar, you'd get at least 5 armor at little cost.
Get Grissenda ASAP. With a greataxe, and 1 point in both cleave and 2 handed mastery, you'll get some much needed crowd control support from her.
If you haven't already, you could do a quick rush to the boss room in Lannegar mines to get the sword of shock (remember to accept the quest 'Head Hunting'). That's a pretty decent upgrade at your level.
Here's a strategy for farming in general. If your 2 recovers are not enough to last you through the entire dungeon, just gun for the most profitable rooms first (hidden rooms and those with sarcophagi), then work your way into the less profitable rooms (e.g. rooms with no chests, or those with ghosts) till you run out of resources.
If you find the difficulty too high to progress, you could refer to this link
http://www.exiledkingdoms.com/wiki/index.php?title=Challenge_Map for a rough idea of where to grind.
For armor stat progression, after getting the bare minimum equipment with armor stat in Lannegar, I suggest working towards these. They're free and will easily last you till level 10+. Leggings aren't included since there aren't really any significant free upgrades at your level range.
Torso: Hardened Leather Cuirass (Random loot in Ydaya Tomb sarcophagi, or 300 gold in Rhoneis), then Lionskin Cruirass (quest: A safe bet) in Rhoneis
Hands: Forest Chain Gauntlets (Quest: A mysterious Letter) in New Garand
Feet: Tolassian Chain Boots (Drop from skeletons in Nayau Tomb in New Garand Farmlands)
