For me I think isolating myself is a red flag that something is up. Particularly if I start not being able to take phonecalls from my parents. Because I never not take their calls unless I've got to the point of not being able to fake "happy". This is for no other reason than I don't want them to worry - so.I guess if I think they'll be worried - there's something to worry about!

Wow. Hadn't thought it all the way through before?!

Great thread!
