Are my frustrations valid about my friends? We were taught to always look out for each other

Hello Guys. I’m a freshman from a medical course (I won’t disclose what kasi baka makita ng classmates ko incase na nasa reddit sila hahaha) and sometimes I can’t stand my friends anymore. Super nakakainis na on my part because they keep asking for my notes when I know that they are not even giving the same amount of effort during discussions because I always see them on their damn phones and suddenly pag may mga quizzes, lalapit sila sakin at hihingiin ung mga sinulat ko. Sometimes they are guiltripping me and sometimes I fell for it and sometimes I just ignore their requests especially on a bad day. But I fear that I cant ignore them for long because I’m scared that they might gossip about me and they don’t want to be my friends anymore (I like hanging out with them… they are truly good people but i just feel like theyre not serious about their studies).

Another problem was that our professors ted talked us and said to look out for each other and “magtulungan at magramayan” considering na mahirap ung course namin at un daw ang need namin mapractice for our profession, so now I cant tell if my feelings are valid anymore or I’m just a greedy bastard.

My feelings are so conflicted right now and now idk what to do🥲
