I'm about to attend university. Over the past couple of years, I've noticed that at school or social gatherings, that i won't talk or interact with people I don't know too well. At school, I go hours without talking to anyone. In fact, in all my classes I rarely talk to anyone unless I'm spoken to. I keep to myself most of the time. I have only a few friends, over the years I've lost more and more friends.
When I get home, my parents most of the time don't allow me to hangout with friends afterschool or on the weekends. I dont know why. I dont go out and do normal teenager stuff like go to the mall or movies. I would if I was allowed to. It's been months since I've actually done something with friends. It's negatively affected me. Also when I get home, I don't interact with my family either. I'm always in my room isolated from the rest. I'm a very shy girl and this social isolation has caused me to become even more shy. I notice that I talk a lot to people I don't know on the Internet as well. Is this affecting my mental health?
