Second I bought my favourite food for colleague bt they dont like it  even never touch it at all maybe is really not nice bt I just having a heart to share I actually hope they will like it..

Thirdly colleague was chatting I was trying hard to join in to them bt I feel being left out,
I am like to talking to myself, maybe I think too much I cant just have negative thoughts , did they hate or dislike me?
Fourth I really dunno how to get along with human I tend to do wrg stuff, I tend to being lame and make ppl hate me bt my main point is trying to get close with them.
I hate myself really..
Fifth last min get trans off to tamp not I not helpful is just I am too tired my boss just cant spare a thought for me I plan to left early just I not yet tell him I have been sentence.
Believe me if I tell him I need some off I can't straight away work all d way to fri he wont let me off...I know him ...he just not someone whom put his thought to staff .
What he care is sales?money ? Whats more..
Really I am sick of life can I end it?
