As a recent graduate, I'm not sure how to advise you. It can feel like having such qualifications is pointless. On the other hand, if you don't have them, you are probably taking away whatever slim chance you had of getting something half-decent in terms of jobs.

How much longer have you got left to study?

If its only a year or two, I reckon you would be better off sticking with it even if you only do grind out an average result.

I know that feeling when you lack motiviation and you feel like you can't really engage in what you are doing. While it is tempting to drop whatever you are doing when you feel like that, when you are in that sort of irritable state you don't tend to make good decisions.

Don't let your mind stagnate overthinking things by yourself. Talk to people about it - your friends, professors or even parents. Even if you know they will have opinions you don't like, its good to look at things from a different perspective and take everything into consideration.
