Can I legally change my middle name to "Burnt Out"?

I'm exhausted :-(

Every week I work 8 am to 5 pm Monday through Friday at the Radio Station.  And 5 pm to 12 am for West Fork Services.  On every other weekend toss in 5 pm to 12 am Friday and 9 am to 9 pm Saturday and Sunday at West Fork and I get 47 hours one week and 78 hours the next week... I'm kind of tired.

I thought I found the solution to my problem when I applied for a Case Coordinator position at West Fork Services that everyone said I was a "shoe in" for.... Don't believe everyone.  They offered the position to someone else and my dreams of actually having weekends off have been dashed. 

I'm beyond tired and exhausted and I'm not quite sure how much longer I can keep up this crazy schedule.
