Currently my husband of almost 4 years and I have been supporting my sick mother and older sister who live with us. We pay the rent,clean,buy the food and home items, pay the bills EVERYTHING. My sister refuses to work and disappears for days at a time while I take my mom to appointments,take care of my husband and attend college. Because my sister was sick as a child my mom doesn't believe she is able to do tasks such as cleaning and cooking. I have tried to convince my sister to work and I've even downloaded the forms for food stamps for her. My husband is ready to leave but I feel like I'm abandoning my Mom. How do I gain a back bone and stand up to my older sister??
