"We" know that if "we" commit suicide you we go to hell...
That is simply your opinion, certainly
NOT based upon the Scriptures!
The vast majority of people who commit suicide do so because life has become to much for them and they are overwhelmed by their circumstances and they see suicide as the only way out!
To suggest that a person suffering from Clinical Depression (or any other mental illness), who commits suicide that God will automatically send them to Hades, to me frankly is highly offensive and really shows your complete ignorance of God's loving and merciful character (Who's first Name is "Merciful," Exodus 34v5,6), who desires
ALL to be saved! Indeed, the character of the person you seem to be referring to (who sends those who commit suicide straight to Hell) is more like that of Satan, who is a murderer and who comes to kill and destroy,
NOT the God of Love Who gave His Only Beloved Son to die upon the cross! Psalm 136, John 3v16, 10v10, Rom 5v8, 1Tim 2v4, 2Peter 3v9, 1John 4v8,16
