Studying means, except new knowledge, many possibilities. You get to know new people, try new situations, and maybe live on your own for the first time or together with friends.
Studying is demanding and may change your thoughts about yourself and others. All this and much more will change us and make us evolve as individuals. All change, being good or bad, can sometimes make us feel insecure or worried. Maybe never before asked questions will arise.
Usually we turn to our loved ones to talk about our situation and our thoughts. Sometimes you may want to speak to someone independent/outside the closest circle. Then you can turn to the Student health care centre where you find social counsellors and a nurse whose purpose it is to give support to the students at the university concerning personal growth/change. You are welcome to contact any of us if you wish to talk about your situation in life.
