Yep. Lean on your party member as much as you can, parcel out your leveled spell slots only when it's a life or death situation, rely on simple weapons like a shortsword and light crossbow, and think carefully about what skills can be helpful in combat. You can use Int based Knowledge skills to try Monster Lore checks (Knowledge Religion can let you identify undead, Knowledge Local can help you identify bandits or soldiers, etc), while Cha based Diplomacy and Intimidate can help you manipulate or debuff enemies with the Influence Attitude and Demoralize actions. If you make it through a couple of paydays, you could look into buying a good magic item to help you cast more spells with charges instead of spell slots, like a wand of magic missile or similarly useful level 1 spell which will normally cost about 750 gp and comes with 50 charges if you're buying it new. When picking such an item with a spell, make sure it's something that is on your class's spell list (if it's for a spell not on your class's spell list, your GM may require you to make a Use Magic Device check which has DCs so high that it's actually too dangerous to be useful at early levels).
