what am I doing here??

[aniunia]

Yesterday I stood in the middle of the classroom, watching the rain, watching kids writing a test... Suddenly i thought what the heck am I doing here? I mean, my job, place where I live. Whole life. It wasn't a bad day and I don't complain about my life every day. Gee, I'm not emo ;P But that thought scared me o.O
Do you sometimes feel the same?...
