I'm not sure I can finger it exactly, but yes depression does cover a lot of things..one of the reasons for me is it keeps my desires at bay so I cannot be disappointed all over again, it stops me feeling "part off" because then I'd have to re-think who I am as my identity has always been so wrapped up in abandoment and rejection so that I think I turn it around on socieity, "It" abandoned me, so I will now abandon "it"...
