Female, 22, looking for a job...

I have a problem.... you see, when I quit my job in SB, I was anticipating 3 more weeks of work, while in that time, I could search for a new job. Well, I was given 3 days and so now it's a month later and I still have no full time job. I have my fantastic job at the Art City Music Academy, but I NEED a fulltime job... and nothing ever seems to work out. They keep giving my position away to another person! It is so frustrating and now I am in a rut. I don't even know where to apply anymore! So if anyone has any suggestions for where I can apply for fulltime employment, with benefits, that has decent pay, PLEASE let me know... cuz I'm dying here! And any serious suggestions would be much appreciated now! Thanks!
