Yes I've been there. When depressed this is part of my self destruct mode. Seek out what hurts and live there. I deactivate my Facebook a lot. I can't handle the "on this day" app but I won't look away. I'll also look up old friends and stuff too. Its awful. So avoiding Facebook helps. As for real life reminders I conciously made an effort to think of anything else. I avoided triggering streets when I could. Anything to stop the reminders. I don't know if thus helps, but I do feel for you.
