Thank you, guys, for all your helpful advice. Thanks for your sympathies regarding my grandpa, that means a lot! I suppose that can be triggering it, but I'm still not clear on why. Also, I should clarify that I did explain to my family the reason why I'm recording them, so that they know that I'm not recording for malicious purposes. So they know about the struggle, and they are trying to help me figure it out, but I probably need to talk to someone soon to try to figure out exactly what is going on and how to deal with it. Have any of you ever known someone with this problem, or is it fairly unique?
