NOSTALGIC

When you recall your college days, you feel happy because it brings back good memories and sadness as those days no longer exist. The word nostalgic basically means to be sentimental and cherish the good times in the past.If you feel nostalgic, you think affectionately about an experience you had in the past and wish things had not changed. It is the good feeling you get when you remember your past. You sit back, smile and think to yourself, wow that was fun or happy.

So, it is a longing desire to go back to a sentimental place, time or to a person's company that always made you happy. It could also mean the state of being homesick or a longing for home.
