A little words - hard to believe

Just last month this blog impression shows up to 3K++ and start this march i drop sudenly to 500 per day and sometimes just 300, i just shock by that and when i search my site on google it sometimes on the last page. Google has it own reason to do what they did but i hope they knew 90% of this blog visitors are from google engine.
Anyway this is a hard time for me, i've been a blogger about 3 years this month sudden deccrease in imression make me feel so down. Anyway i still continue to blogs and hope google listed my blog in search result as before.
(really tired)
