What is the way to overcome the inner struggle between performing acts of obedience and avoiding sins, and the feeling of despair?

One must distance oneself from the internet when faith is weak and desires are strong to avoid what is worse, and cut off one's connection with it except in cases of extreme necessity. This is considered the first step on the path of repentance, and leaving a corrupt environment is one of the reasons for steadfastness in repentance, as in the Hadith of the man who killed a hundred souls. Seize the opportunity of youth for obedience, and be patient regarding disobedience. As for thoughts of suicide, they are from Satan, and they do not relieve the pain of sin; rather, they lead to Allah's wrath and painful torment, as stated in the authentic Hadith about the recompense of one who kills himself. Beware of whispers, seek Allah's help, and strive in supplication to purify the heart.
