Medical and housing expense

I lost alot due to co-vid 19. Had to put cats in "kitty foster". I lost house and truck. Became homeless . Slept behind "tire kingdom". Very awful and scary. Stayed in a portable shed at a famlies back yard. Unemployed 5 months, finally, a job opportunity came along. I rode a bike 2 miles to woodland blvd. Caught bus to get to 2 nd bus at publix grocery. Got off bus in Daytona Beach, walked an additional 1 mile to get to job.. I repeated going back home. I also lost my mama, August 18th. Saved all my money and FINALLY got a studio in Daytona Beach, to be close to work. Got studio and cats back. Been a long road. I percivered. However, as I type, I went to 2 hospitals with servers pain. 1st hospital was not thorough. 2nd hospital says I have shingles, but, after several days, I do not have all shingles symptoms. I've missed 3 days of work. I pay rent every 2 weeks, $437.50 equals $875. I paid my own $1300 to move in. I have a balance of $400 @ $25 payments till paid off. I am in GREAT FEAR of losing my home again. I am going back to Ormond hospital to try again. I still have pain under my left breast/rib cage. The meds they told me to get for shingles came to over $200. I cannot attempt to get them till I know for sure diagnosis. I need help keeping me and my cats from being homeless again and being separated AGAIN. We couldn't go through this again. I worked so hard to pick myself up again. I do not want to fail again. My boss is being great but, I'm sure my NEW LANDLORD will not be. Just want to keep my studio RENT up, get any meds I need, few necessities for me and cats. Nothing more, nothing less. Please help me not fail!?!?
