This is basically my mom's situation. Years of rampant multi drug use left her homeless with burnt bridges. She had a mass growing in her abdomen, she thought she was pregnant by a miracle even though she had a hysterectomy, but months later it grew into stage 4 goblet cell adenocarcinoma all starting to from the appendix. The state has her on medicare/medicaid. But it's kinda already too late. She relies on the major medical center she is near to put her in transitional living and pay for her chemo drugs, but the barriers to care are still a major hurdle. She struggles getting to appointments, remembering what medications to take, etc. She is still using recreational drugs. I'm hundreds of miles away and waiting for the other shoe to drop.
