feeling upset n heart-broken

it had been a long time since i blog again but i have feeling so upset and moody these few weeks becos of my fyp project. Although it is coming to an end and our group should be happy and celebrating, but it seems that our 3 yrs of friendship r coming to an end too. i have been feeling so "outcasted" these few weeks and i think just becos of that box. is our friendship taken so lightly that it doesn't worth a thing just becos of that misunderstanding... i really duno. u nv know how i feel when u all meet up and enjoy while i am kept in the dark about it. it was only during another of our gathering and u shared about all those fun moments but i knew nothing about it. then i would rather not know if u had nv meant to ask me along. I am not being petty about all these but i would rather u have told me and talked things out. Am i not one of your group? physically i seem to be but emotionally i dun feel so. i feel that i am just an extra and is so unimportant in this group- i am just being there becos i am your grp members, no emotional strings attached. everything that was important were taken by u all, all i took was those minor things that wasn't worth a heck.
u can nv know how sad i was when u told our advisor that u were going to gif that box to them and it was like 3 of you knew abt it and have already decided. I did not know anything about it at all! when i sounded so disappointed, all of u were like : "Fine! we can also come up with another one without you!" and all these negative feelings came up. all of u worked on it quietly as i had to pretend nothing happened.
u nv know what i went through when i came up with the box,i had injured my hand and back. so i treasured them very much and wasn't willing to give up the other box either for the school.
now i am thinking, should i stay on with this grp for our degree too since i felt so unimportant and not being valued. i am having lots of second thoughts about this trip, our degree programme and the work. tomorrow would be our last day of poly life as i duno how should i be coping with all these mixed feeligns within me. yes, i would be upset and all those teary moments. but how about u gals, i really duno. i treasure this friendship dearly but how abt u?
