I've been on the receiving end of guilt trips from my (now deceased) grandmother, and it's not nice. The best thing I ever did was to realise that she would never change. I cannot control what others do, only what I do. So I decided I would simply let her rant and carry on, nod and smile, and just ignore her bad behaviour.

The rest of the family knew she was behaving badly, and that her behaviour would never change, so rather than create a stressful situation by expecting an 80+ year old woman to change, we chose to ignore her behaviour and focus on our own. This did mean taking time out away from her so we could vent amongst ourselves.

It might sound callous/heartless, but it worked for us.
