What you just described is not a friend.

Also try to keep yourself busy with something.

I had a 6 to 8 hour part time job after school, never once thought that I needed friends at school.

If you have a specific hobby or sport you like it's easy to find like minded people.

I get it, making the right friends is tough, some times it takes time.

As an introvert who really is not a social person Try to set boundaries with her step by step. Also if there are others in your year who are quiet they tend to be good friends just like you it’s just hard to approach people
