I am sorry I cannot find an article I read before. It is a pity it was in Spanish, though. It is a question a daughter sent to a psychiatrist online. She said her mother is under depression and started to isolate herself. They, the children, are pushing as hard as they can, but the mom isolates herself even more. The mom does not want to go to a doctor or anything like that. Then the psychiatrist online says stop the pushing treatment . It is clear it is not working and even though you love your mom, perhaps it is your anxiety anticipating the guilt you would feel if something bad happens to your mom what is driving you. Many times people with depression need space and time to face their depression. You can still make her feel you are available and check on her often without being pushy.
