Two months to go on my masters programme and I want to drop out what should I do?
My heart goes out to you, it sounds like you're really unhappy with your current situation and feeling very conflicted.  

It's hard to give someone advice on a topic like this because it's so personal so instead I'll give you a few of the questions that I might ask if we were able to sit down and have a chat about this. 


What initially led you to apply into this masters? Is it your specific experience that is creating problems or is it that this masters does not align with your interests/goals?
What is the appeal of this job offer? Can you really see yourself doing that kind of work or is it that it represents a face-saving alternative to completing your masters?
What would have to change for you to be comfortable completing your program? Is it a change of dissertation topic? Is it extending by a term or a year to take the pressure off? Changing supervisors? All of the above? 
Are there jobs that you want, now or in the future, that you can't have without this degree? How important are they to you?
Do you really hate your program/subject or do you hate the situation you are in?


Think on these on these until you hear back from your school and your potential employer. Once you have answers to them, take a break and step away from it for a little while; when you come back to it see if you still feel the same way about your answers or if your thoughts have changed. 

There's no right or wrong way to do this - I personally trudged through a degree when I knew it wasn't right for me because I was so close to the finish line. Finishing that degree proved to me that I could see something through to completion (something I had always struggled with) but also kept me from finding my true path for another year. I'm still not sure what the right choice was, but I'm happy with where I am now.
