I hear ya :( It doesn't matter if they're close friends or barely even acquaintances, it seems to just fly right by most people that artists have a hard job and put in a lot of effort, experience loads of frustration etc.
And it sucks, 'cause even though you know it doesn't really matter what these people think, it still gets to you. But hey, if you're lucky, it also means you never have to get a "real" job and get to do what you like, so overall a pretty good business ;)
mostly because I've been feeling like crap, but I'm still writing.
Urgh keep on writing <3 I know how hard it can be sometimes, particularly if you're feeling down because of other things, as well, but in the end, not writing will only make you feel worse, so...
And, regardless of naysayers, I always will.
