am I losing myself?

just dunno why recently there are a lot of thought that is going through my mind, be it to the smallest thing or to the very profound philosophy... yea and I am already halfway through my second semester of my uni life and still it is as stress as ever.. been under this kind of stress for almost a year,  it makes me kip on think of this question : after all what am I looking forward in my life and what do I really want to achieve? coming into sg to study undoubtedly is for its prestige and maybe a better earning in sg after I graduate. but then everything in this world doesn't come free. In exchange for this is the huge debt that i will be carry once I step out if my uni, and nevertheless the never ending stress that I will have to face with.. ever since enter the uni, I have been under stress and I have sacrifice a lot for my study til a extend that I really feel sick of this. And I always think of this,  doest it really worth it for me to be as so in exchange for the so called better future? well I really dunno for the time being.. maybe I am still immature that's why have this kind of thought ba.. another issue that I have been facing recently is that I feel I am losing myself haha I also dunno what I really wanna express by saying this @@ well being in such a competitive uni where all the top talent from all over the world gather, I feel myself am such a ordinary person and sometimes, lousy and useless. ok that's all for today although may still have tonnes of things to say but that's it for today...
