Hey, you sound like me! I'm a cancer survivor twice, a glioblastoma and a malignant tumor on the roof of my mouth. I also prefer the comforts of home, I do my shopping in the middle of the night when the store is empty. I'm not agoraphobic, I just don't like being around people. Welcome to Steemit- it's great here, nobody even knows what you look like unless you want them to!
