My dad has lung cancer and has recently turned into a very needy, no shame, depressed person. He comes over unannounced and let’s himself in after a quick knock just to “get a hug”. I love him so much, but my spouse especially is getting irritated. This has become a daily routine for all 5 of his kids. He currently lives at my sisters and sometimes makes his rounds twice! He doesn’t respect my privacy even though I’ve told him it makes us uncomfortable he ignores my requests. I hate the thought of upsetting him as he is a Vietnam vet and recently started struggling with nightmares. Since he also has lung cancer, I really don’t want to upset him because he is also very depressed. I have become ill myself and the constant stress is not helping.
