I need some help making a decision that could change my life... CAN ANYONE HELP????

Ok so I am 15 years old and am going to be starting 11th grade in August but the thing that I don't know now is what school I will go to. So my câu hỏi is what school I should go to tiếp theo year? I'll give bạn some background on the pros and cons of each school. The school I'm at now is great there are lots of things that I like about it that is way I chose it in the first place. Plus I have all my Những người bạn there. For me this năm has been really tough. I had to deal with a lot of loss this năm and I got rather depressed. I am the kind of person who is really closed off and do not express my feelings and I rarely share how I am feeling. So when I went through everything that I did this năm I realized how close I really was to all my Những người bạn because they made the last few months so much easier for me. So then the other school is also a really great school and when I really think about it I think that in the long run moving to that school will give me a better shot for my future. Yet I don't have any Những người bạn there so it may make it difficult for me. So basically when I think about staying I think that I really want to go through all the high school stuff with my Những người bạn like prom and graduation, but at the same time I think the other school will be better for my future. When I talk to my Những người bạn about this they just tell me to stay because they want me to stay at the same school as them which just makes things really confusing for me.

So I know that there is a lot of information but I just want to get an idea of what other people think. I need another perspective that is not bias to one side. So if bạn could just leave your thoughts about what bạn think I should do if bạn need thêm information about the situation just let me know and I'll give it to you.
THANK bạn VERY MUCH I REALLY NEED THE HELP :)
