Frustrated

I hate it that life is getting in the way of my writing. Working three jobs has dried up my creative juices and no matter how hard I've tried, nothing flows. Every time I try to write I get mentally exhausted within moments. Writing used to be fun for me no matter how bad I wrote I liked doing it. Now, when I try to sit down and write it is like a chore. It doesn't help that a flood destroyed a LOT of work I had done. Somehow I've got to find my writing mojo again. Any ideas?
