Asalaaamualaikum Warahmatullahi Wabarakatu,
Subhan Allah, you HAVE to stop. Why do you want to do self harm after Allah (SWT) created you in the best form?!
If you kill yourself (Astaghfirullah), then you will be in Hell forever! The life of this world is only a test! You have to remain patient and make tons of duaa and read the Quran and ask for forgiveness!
"And this life of the world is only amusement and play! Verily, the home of the Hereafter, that is the life indeed (i.e. the eternal life that will never end), if they but knew." [29:64]
The Prophet (SA) 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."
Anas bin Malik (RA) reported Allah's Messenger (SA) as saying: "None of you should make a request for death because of the trouble in which he is involved, but if there is no other help to it, then say: O Allah, keep me alive as long as there is goodness in life for me and bring death to me when there is goodness in death for me."
Allah's Messenger (SA) said, "Do not wish for death, for the terror of the place whence one looks down is severe. It is part of a man's happiness that his life should be long and Allah Who is Great and Glorious, should supply him with repentance."
Allah (SWT) says in the Holy Quran:
"...And do not kill yourselves (nor kill one another). Surely, Allâh is Most Merciful to you.And whoever commits that through aggression and injustice, We shall cast him into the Fire..." [4:29-30]Prophet Muhammad (SA) said: "Indeed, whoever (intentionally) kills himself, then certainly he will be punished in the Fire of Hell, wherein he shall dwell forever." [Muslim-Bukhari]"And certainly, We shall test you with something of fear, hunger, loss of wealth, lives and fruits, but give glad tidings to As-Sâbirin (the patient ones, etc.)" [2:155]
Allah the Almighty said: "O son of Adam, so long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shall not mind. O son of Adam, were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I would forgive you. O son of Adam, were you to come to Me with sins nearly as great as the earth and were you then to face Me, ascribing no partner to Me, I would bring you forgiveness nearly as great at it."
