I never feel the taste of happiness and always think about suicide?

Happiness lies in faith, piety, and good deeds, and among the greatest causes of misery is turning away from Allah Almighty. The remedy is achieved through two aspects:

1. Purification and emptying: Through sincere repentance to Allah Almighty, avoiding everything that leads to sins, and getting rid of bad companions. 2. Adornment: By being diligent in acts of obedience, preserving obligatory prayers, especially Salah, frequently remembering and thanking Allah, and associating with righteous women.

As for suicide, it is forbidden in Islamic law and incurs severe punishment. One must flee from it and beware of even thinking about it. Ruqyah (Islamic exorcism) and regular remembrance of Allah are recommended, along with seeking help from specialized doctors when psychological treatment is needed.
