Am i Stress??

Haiz..................................................................................................!!! Lately my friends said I look thin already. In fact, in comparing myself with previous, I really getting thinner than before already! But the reason for this I really dunno. Some friends said maybe due to over stress?
Then I started to ask myself, is it I feel very stress now?
What am I feel stress with?

haha... so many dots mean i also dunno what i feel stress with!
Or maybe i always think about many things just that i didn't realize until it became stress in my life. One more week i will reach 21 years old. Yet, i still behave like a kid all the time, am i just pretending to be a kid? I just behave like a kid because i scare of lonely and like this can attract many people to come chat and fool around with me?
Maybe...
Until that, actually there's another of myself, where the one always think about many things, worry all this and that, and the worse is soon will have infantile autism (自闭症)! (Although my friends said this absolutely WONT happen on me! :P) But who can predict the future? No one can do this...

Stress are everywhere! But at least i must find a way to get rid of this! We cant 100% deal with 100% stress , but we can try hard to deal with 99% stress, many the 1% stress we wont able to get rid off it for sure..

At last, i still want to know, WHAT AM I FEEL STRESS WITH WOR!!!!!!!!!!!!!!!!??????????????????
