pathfinder 1e – What resources are availabe to improve my vanilla cleric archer?

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. I feel like enhancements are absolutely obscene in price, or so useless they don’t do anything. I haven’t found any useful magical items within my price range.

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 Asmodeus 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.

This is my character:

  • Dwarf Cleric (no archetype)
  • 12-Str 15-Dex 18-Con 12-Int 20-Wis 10-Cha
  • mostly focused on healing with the Healing and Good domains
  • Channel Smite and Guided Hand as my two feats
    • breastplate armor and a composite(1) longbow

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?
