Is suicide similar to Nibbana? I read a comment on this forum, which said: 


  why do you even need to work hard attain Nibbana? Why not just commit suicide when things get tough?


This comment gives me the impression the writer believes there are some similarities between suicide &amp; Nibbana. 

My questions: 


What are the reasons why people equate suicide with Nibbana? 
Why is Nibbana totally different to suicide?
