not feeling well

what is really happening to me? i don't really understand what it is that i'm feeling. do i feel sad? do i feel empty? i don't know. it feels like something is missing. i'm not really sure if this was caused by our goodbye. i don't know. should i be sad over someone not worth it? probably i have gotten used to it. the pain is always there, now that we have put an end to it, should i be happy now? hayy..i have to train my mind..
