help.

not understand what I'm feeling now. Random things around my head, mixed until it crack my brain. It's not about my deadline, it's talking about "Why I'm thinking too much". I make a wrong decisions and can't solve anymore. Whether this problem can be over ?

I try to fix it. Someone tell me to talk first, but I say it's not about a challenge, it's something lost and Someone replay my conversation, if that guy dead someday, what will you do ? you don't have time to apologize ? so I said, it will be okay and He will rest in piece. 

And guys, if you read what I posting tonight, it's not effect biochemistry journal, it just about something missing, and I'm tangled in this situation. Someone help me !
