Mahbub Shaheen, a student of Dhaka University, posted a suicide note in Facebook  at 7:08PM on 2nd of June, 2014. He wrote:
I am lying on Rail Line. The Train is coming. And I am going to kick out bloody myself, the useless eater.
Once I've posted a comment “I should leave” then after I posted “I have to leave”. Some of you asked me- “From where & where will you go?”
I don't know where I am going. But I am leaving. Leaving useless myself forever.
Good bye, good bye forever.
In the comments section of the above post it is revealed that his friends tried to locate Shaheen who was supposed to reach Dhaka, the capital by a train by the evening. His mobile was unreachable so they tried to inform police  and his family but did not know how. A few hours later someone confirmed  that his body was found near Kamalapur Railway Station.
This shows that Bangladesh desperately needs an effective suicide prevention hotline to act quickly and save people like Shaheen.
