weighing my options

I've been assigned a project at work, and its opened new chances and opportunities to learn. I am immensely grateful to my boss for that. Except that, there are times wherein I have to double duty and do what I was doing before I was assigned that. So with the mix of deadlines of the new project and the need to deal with clients and do the over the counter transactions, I feel worn out. I don't know how much more I can take. I think it's time for me to move to a new environment. There are some elements in my current workplace that just stress me out. I try as much as I can to finish what I am supposed to do, but I don't see any appreciation for it. So, why stress myself, diba? I am going through my options right now...go abroad or find a new job here? I want to get a Masters degree and I'd like to experience living on my own for a while. But, experience-wise I think that I'm still unqualified to get a Masters. Hmmmm..... Tough decision to make.
