The cycle of psychological suffering !

I am frustrated.. I do not feel happy... The review cycle has begun at work and people are expected to write strong points about themselves and give "valuable" feedback about others. People tell me its no big deal.. Its a part of the corporate world.. but it annoys me..

The first question in the appraisal form........
What are my major accomplishments for the past six months?
Its been 3 days and am still staring at the form... I am sure if I was Obama or may be even a part of the terrorist group in Pakistan i would have something to pen down. The past six months all i did was do the work assigned to me and learn some new stuff which looked interesting. I did not go EUREKA or shoot down a terrorist.
I am still staring at the form !!

What do I feel are my greatest strengths in this position?
Do they want me to quit out of shame? :(
I mean already its difficult for me to talk positive about myself.. and now i have to like write it down and it will remain as proof for years to come :|
My manager will ROFL after reading it.. and say ya rrright !!!

Are there any changes I would like to see made in my job that would improve my effectiveness?
hmmmm.....
okay...
I am supposed to know that?!?!

I mean people... come on... give me a questionnaire and i will say agree or disagree. Do not do this to me!! :(

After great difficulty and using my low writable skills i somehow fill up the form and ask my "friend" to review it..
He says...
The matter and the language is well below your standard !

Now.. am back to square one.. am depressed.. and am clueless why am doing it !!
