I agree with Heatherzart "Get over it". But I think if you're feeling things are slow then it's your job to get things going. You have a few irons in the fire...maybe you need a lot more. These opportunities are never going to come to you, you have to make them happen, especially in this economy. So what are you going to do? Research. Who is making it happen and how. See what's working for them and get in on it. Beg, borrow and create opportunites for yourself. The only difference between the nationally known artist and the artist next door is marketing.

It's a really exciting world out there, full of opportunities. Go for it.

A very successful artist in Washington DC once told me to "get over it" and I'm going to say the same to you.  And I don't mean this in a nasty way - I mean it in a good way.  Shake off the negative and move on.  Focus on the things that are going well.  So these people didn't call when they said they woul - get over it!  They weren't worth your time then.  Focus on the fact that you have an upcoming exhibition.  Think of the THOUSANDS of artists out there struggling to get their work seen and you've got a gig.

Nothing ever moves as fast as we'd like it to and that's just human nature.  So I think it's natural for you to be frustrated and feel like things are dragging.  So my advice to you is to take stock in what IS going good and focus on that.

Congratulations on taking the big step and becoming a full time artist!  That's a brave thing to do but your work is fantastic and I think you'll be successful.
