Life always comes with hardships. We will all go through hardships and tests, however we shall remember that Allah (swt) does not leave his true believers misguided.
If you feel down that you are even thinking about suicide, it is important that you deal with whatever makes you feel this way. The first step to overcoming suicidal thoughts is to seek help from professional counselors and get closer to Allah (swt). This will assist you in dealing with whatever difficulties you are facing.
Remember..suicide is indeed a major a sin.
“Narrated Abu Huraira: The Prophet (PBUH) said, ‘Whoever purposely throws himself from a mountain and kills himself, will be in the (Hell) Fire falling down into it and abiding therein perpetually forever; and whoever drinks poison and kills himself with it, he will be carrying his poison in his hand and drinking it in the (Hell) Fire wherein he will abide eternally forever; and whoever kills himself with an iron weapon, will be carrying that weapon in his hand and stabbing his `Abdomen with it in the (Hell) Fire wherein he will abide eternally forever.’”(Bukhari)
