No really anything that I could buy with my archer-based cleric. (1e)

I am in a relatively new campaign (level 5) and I just came into about 9k gold. I am a cleric and there is pretty much nothing I can buy that I haven’t already. I have 12 str, so no more than a plus one on my composite long bow. I have a nice set of hide but low dexterity, so no more medium armor worth buying. All enchants are absolutely obscene in price, or so useless they don’t do anything. No magical items that I can use are within my price range, and the worst part is, I feel absolutely useless in my group. My spells do virtually nothing, my bow cant hit anything because I CONSTANTLY role like Satan himself is channeling his personal hatred towards me through my dice, and I don’t have enough strength to be anything but a minor inconvenience to most melee enemies. I know I probably am missing something huge, but are there some things people could recommend for me to buy to be remotely helpful for my group?

For clarification, I have 12-Str 15-Dex 18-Con 12-Int 20-Wis 10-Cha. I am a Dwarf, just a classic cleric, mostly focused on healing with the Healing and Good domains. I have Channel Smite and Guided Hand as my two feats. For gear, I have a normal set of breastplate and a +1 non-magical composite longbow and all the rest of my gear is normal adventuring gear. I have no magical items.
