Scary Feelings Inside Me

I was playing some PC games as i were bored jus nw.. But suddenly alot of things came into my mind & i started thinking it non stop till i feel something in my heart.. Duno y i feel so empty inside.. Not sure if i can describe tt as "Empty", but jus cant think of other words which can describe this feeling best..

I went to a friend's son's 1st yr birthday yesterday.. I met up a gd friend of mine at Parkway Parade to buy present first.. When on the way to East Coast chalet in cab, suddenly we mentioned abt some pple in our sec sch.. Most of them were already married & has their own family.. My gd friend is 1 of them as well, married & had gave birth 2 a child.. I asked myself whether i'm hoping to get married and have my own family..?? But the answer is a definate NO !! Aftertat i thought to myself, maybe it's because i feel tt i'm way behind them.. Not in the sense of comparison of course.. I jus thought tt they had already started their 2nd stage of life while i'm still here feeling forbear towards marriage, wondering wad kind of man would i chosed to be with the rest of my life & hw will i be in a marriage life.. I feel lonelier & lonelier when my surrounding friends get married 1 by 1... Conversation & topics would be different.. Somehow feel tt they r from another world..........

**How do u describe this feeling if it was u...??
