We are quiet young to handle all our problems by ourselves as we lack experiences. I sometimes really miss my school friends and their support. I have not been able to get over my school phase completely. Probably because I have not found really great friends here?
You can try to seek guidance whenever you feel doubtful about your decisions. It takes time for almost all of the students to adjust into a new phase of college life after finishing their school. You should encourage yourself to participate in the various activities in the colleges. You can become a member of the different societies or clubs of your college. In this way you will be able to communicate better with the people and surely you will make good friends.
