guilt

hello everyone, my cat fatgirl passed last month and i’m feeling really guilty, i’m only eighteen and couldn’t afford to cremate my fatgirl (cremation is 300-600 where i’m from), but my family is moving in the next couple months to be closer to family, the guilt comes from the fact im contemplating leaving my fatgirl where she is and not disturbing her resting place, i dont want to leave her behind but i would feel like a bad person digging up my cats bones and then hauling them on a ten hour drive to our new house, im sorry if this seems like a weird post, ive never posted in any reddit threads, i just need some advice.
