emotions..mood swings??!!

i've been too emotional n having moodswings nowadays..
i dun understand this... what is this tiring period i'm experiencing? i dying to get it over..

i could be happy but feel sad the next minute..
i tried to be strong on the outside but inside me i was overflood with tears..
i feel this way deep inside my heart but what came out from my mouth was not wat or how i want or feel..
i can cry n cry non stop...its very tiring..
grr i'm losing myself.. i dun used to be like this... i dun want myself to be like this...
i dun understand myself anymore...
i feel so sad..

haiz i guess i need some rest... a break probably..
