Scared of this feeling

I don’t know but something is missing. This is it, third year ends, the most difficult year of the engineering life, as per said by some experts. But why is there is something in me which doesn’t wants this to end. I see my final years, their process of bid adieu and somewhere it scares me.
I am enjoying my life at fullest. Responsibilities may be not a word to be included in my dictionary right now. The struggle to get marks, to raise pointers, these things has always been a headache, but the small segments of ‘BAKAR’ with friends never made it look too big.
The next year birthday would be the last one where my friends would make me regret my birth because they wouldn’t be there to take my GPL.
May be I am too emotional and this is too early to think these things but a feeling of not seeing my everyday from last year drowns me and scares me.
