Feeling an Extreme Need to Vent

So I really try not to let unfortunate individuals darken my mood, but sometimes its simply unavoidable. What is particularly frustrating about this particular incident is that I effectively don't have anyone I can vent to because I'm trying to shut off all contact with the person. The person first said that I wasn't a real artist and that I never make real work and that what work I do make sucks. Then this person recently made fun when a friends got mad at me for expecting her husband to show up for a project we're supposed to be partnering on when he's working on other projects instead. I really don't get people that go out of their way to tear other people down.

 The individual in question isn't even a visual artist she's a fucking writer.  What the fuck does she know about the quality of my photographs or paintings? And excuse the fuck out of me that right now I only have the money and space to draw in my sketch book and take photos with a digital camera. Admittedly the picture up top is something I took with an iphone but I've been getting really curious in exploring the medium and the cultural connections surrounding it.  I think it adds something to the picture knowing that it exists purely in cyberspace and was taken with a camera that isn't supposed to be good for anything serious and yet looks like a very professional photograph.
