well i can understand how you are feeling right now because i'm in the same situation as you are....
i feel very confused because i wanna be a good professional in the future, but if i want this i should study,,,hhehe my mind is a mess..
i just wanna give you an advice..when you stop studying and you begin a job, is a very huge change, i mean: you're very young and you have a great future ahead of you,, so you should study hard, i know is very difficult and sometimes you feel a big pressure,and you're very stressed about all the studies' stuff,but you should think of this way: when you finish your studies you'll be a professional..and a professional earn more money and has more work's proposals in major companies than a unprofessional..
there is no haste, i know you have much to give..you can get the best, just follow the good advices and listen to your family, they can help you, you're not alone.
best wishes to you,
