Help save Squid!

Squid is about 6 weeks old, she was found at my work abandoned most likely because of health issues caused by weaning too quickly. She has a minor anal prolapse because of this. I am 16 and only work 3 days a week and cannot afford to bring her to the vet to get this issue fixed. ANYTHING helps, Squid is actively eating, drinking, and playing but I fear that if the prolapse is not corrected soon that it will get infected and get worse.
