Stress and challenging

I lost my future way recently just dun know what to do for my next step. I not sure about my potential as what i am interested in just feeling that being a doctor is quite meaningful for my life . Is that the reason for my own interest ? I am thinking what come to my life next ! Some of my friends already decides their ways for future i just know i cannot make wrong for the decision because i have to save my time and money for my further studies . I cannot share this problem with my mum since she will tell just choose whatever i like to be while i tell my boy friend he will say whatever decision u make i will support you . I know i can handle the pressure well which i feel that some signal is coming to my daily routine that is my mood . I cannot really enjoy with my friends because thinking the syllabus left to be studied on night , preparing our syllabus for the next class , mid term text or even our final . All these things i can make it perfect if i work hard for it just the thing i am confusing is my future .. .. God just give the way i should for it ..
