Triple bypass in right leg

Hi, my name is Spirit Seneca. I was operated on Dec 12th, 2023 for triple bypass surgery on my right leg. Operation was 13 hours. Went to a rehab center after ICU and am now home trying to get better. I am unable to walk without a walker and am in a wheelchair. I have not worked for some time now. I truly would appreciate any assistance you can provide to me. Unknown at this time how long my rehab will take. Also toes on right foot turning black. Unsure of amputation at this time also. Please help me. My bills are piling up. Work as a waitress. Thanks in advance. I’m 73 years old.
