New Job New Beginnings or New Job Run Away!! ?

I have been working at a new job for about 3 months and I really enjoy it. It's a medical malpractice insurance company the pay is GREAT, but lately it seems all the work has been coming to me. Everytime I turn around my boss is assigning me a huge project to do on top of other things and then takes tasks away from other employees and mentions that I can do it. I've been feeling a little overwhelmed. Is this New Job New Beginnings or New Job Run Away!! ???
