It is a common problem that you don't get along well with the students in your new school. So I want to give you some advice.
First of all, be as confident as possible. Nothing is more attractive than a person who has a positive attitude towards life. Secondly, make eye contact with others, smile at them when they look at you, and smile when they say something interesting, which will make you look friendly. Third, invite others to do things together. For example, you can invite them to chat. It is better to develop and share your interests with them.
Last but not least, don't be too hard on yourself. It takes a lot of time and effort to make new friends. You should be patient.
Best wishes and good luck!
Yours,
