Hello my dear friend!
I hope you ARE DOING GREAT .
I am so sorry to hear that you are not happy at your new school. I do hope soon you will like your school.
As for me I think it is normal to feel apprehension when you change something in your life and this change is great. 
I think you should be more patient and try to find new friends. You are so outgoing and friendly I think it won't be difficult to make new friends. 
As for teachers I think if you do not understand something you must ask them to explain it after lessons.
I  bet you will manage with it ans soon you will write to me that everything  is fine.
Please take good care and write back.
Yours friend   Kate
