Feeling a little down, how can I make myself happy for tomorrow?

Ok mate, good points. However, i've moved 8 times to different countries and i'm 16. Now i'm back in England for good (where I started). I remember the sadness that swept over me for a while from leaving each country because of having such good friends who i had shared a lot of memories (whether it be the first cigarette or drink etc). But, I was always ready for a new challenge and always ready to adapt. One point though, never ever change who you are because i've been back here for about 6 months and i haven't changed since i was a baby because of anyone. I am quite popular in different communities aswell (sports, school, neighbourhood, music and the Armenian community because of my roots) and i always have been. bottom line: adapt but don't ever change.
