You still have a job and that's what matters. You're doing a lot better than most addicts because we can't hold a job or keep a stable home.

I love weed but it makes me lazy. Maybe that's why you're not able to get your master's degree. You said you spent most of the time before exams getting high! I bet if you lay off the weed just long enough, you'll be able to get your master's degree in no time with the credits you have already.
