question: i am now in my first year in college.. my problem is that i usually forget my lessons quickly.. not that quickly but after about two days, i cant remember what we have discussed earlier..  i am also having a hard time recalling simple things, aside from my lessons,. i am not like this two years ago,. those days i have topped my class but since i had this problem, i seemed to be just like an ordinary student,, do you know whats happening to me? i am so depressed..
