hello
@loner
welcome to DTP
sorry you are having a tough time
might you have a chat with the adults in your life, maybe show them your post
at school, I think you will have a form tutor, or year head, or counsellor, or a favourite member of staff ... ask to have some time with them and let them know your concerns, they will listen and do what they can to help ... if you are not sure about talking with them, drop them a note and ask to meet one break time or lunch time
it's good that you are wanting to study ... the other students may be surprised at your new maturity and not sure how to take it, it's confusing sometimes when someone changes their outlook, we tend to expect people to stay the same ... so it may take a bit of time for them to come round ... could you join a club with new people, so you share an interest
