My plate is a little full

I dont know why I do this to myself, but once again I have too mutch on my plate. I ve been struggling thru a costuming job all summer with two costumes out of 9 complete. I design and sell lampwork bead jewelry at craft shows, doing 3 this fall. I am a freelance illustrator and have at least 2 art calls per month sometimes 4. I have a 22 hour a week job that actually pays the bills. Ive been overwelmed all summer and not able to focus on anything... I wonder why...? I need to answer every art call ... this is the only way to get a bigger quarterly royalty check. I can make about 60.00 per hour on the jewelry (when it sells) with out the craft shows I dont sell that mutch. ugg!!! gotta finish the costumes....
