Can you suggest something?

Hi frds... After 1month perfect preparation for Ca final 2nd group, m feeling so much of tension and fear from past 3 days. I couldn't read properly, i couldn't concentrate. I was so confident earlier but now I jus dnt want to write because m not ready to,face the result. i failed in last two attempts for second group with 194 and 187 marks. I passed 1st grp earlier. This is my last chance to make my life time goal happen. I postponed every little happiness in my life for the sake of CA. Totally m frustrated now. I prepared better than what i prepared for last attempts but I couldn't concentrate. From 3 days my thinking got so worse till I commit something either not to write or to die. please help
