Barely functioning as a 1st yr

I am a bit scared and anxious rn. Back in college, I can get good grades na puro overnight or same-day reviews lang and still maintain a scholarship. I lie that I study kasi nahihiya ako, pero it worked for me. But now that I'm in 1st yr med, it's hitting me sobra na mahirap na walang nabuild na study habits. I am the type na 24/7 sleepy and listless. I do not like forcing myself awake, never ko kinalaban ang antok. I don't drink coffee, tea or anything else to keep me up. I don't study unless I get that sense of crisis. Ngayon ko lng naisip na I don't like the character I've built for myself before going to med. It's hard. I rlly want this but at the same time, I need mega adjustments and I'm just scared of failing exams in the process. It's not that I overestimated myself kasi I know I'm not that smart and I've always just wanted to pass. It's just that nadadagdagan yung goals ko but I can't get myself to function for the longest time already.

Please drop some advice or help bec. I feel so alone with this and I'm scared of being judged by my friends. I am also considering asking for professional help to cope better pero I'm still not ready in many ways.
