What do you do when you loose all hope?

Well I just changed schools on my Senior year. And I miss my friends, I have friends in this new school. Everything is different. People are different, teachers are different and I feel like an outcast. This has made me loose all hope, I used to get very good grades in my old school and now, I've lost all hope and my grades are getting lower and being in this school has made me very depressed.

What can I do to cheer myself up? I've tried to write alot about this but that doesnt seem to be helping. And my old friends seem to have forgotten me, or been to busy for me.

Help.

Being alone to much will only isolate you and make things worse. Maybe you could talk about your old life with your new friends :D tell them what you miss about your old friends, they may try and help you with this. Join some clubs in school, things you enjoy. Go out and enjoy life your free and young go have some fun dont drown yourself in your sorrows, life is a challenge you have to fight for the things you believe in. Smile :D :D :D :D
