Aww, ((hamstergirl)). It's ok, we're here for you. Honestly, don't feel pressurized into feeling happy all the time, or made to feel guilty because you're not. Doug's disabled friend may just have a different temperament to you, or more likely, he's a very good actor and puts on a shining front to the world whilst in private maybe he's just as depressed and despondant as you...
I really really hope that there is nothing else wrong with you, but if there is...well, it has to be faced, unfortunately, but you've got something wrong in your post ok. About able-bodied people believing disabled people are practically superhumans. Well we don't (well, that is, me and hopefully everybody else on this board, and perhaps a few in the real world too), and we know you're just as vulnerable as everybody else, in fact more vulnerable, and that you don't have an unending vat of courage that you dip into now and again, but that you're lonely and scared just like everybody else...and you're entitled to feel that way too.
Oh yeah, and feel free to email me, I've been missing you! I sent an email to your cyberus address about two weeks ago now, and I've been worrying about what had happened! But I know you're ok now
