People like this really wind me up! I have a friend who does something similar, though not in relation to depression. If I mention anything I'm interested in or that's a problem she tries to take it over and offers lots of unwanted help. But she's a lovely lady so I've got quite adept at ignoring her or steering her in another direction. If she offers to do things I don't want I just never fix a date or I find I'm always too busy. I think it boils down to her having problems of her own.
