I don’t have the desire to do good actions. I feel no eagerness and motivation for acts of worship and Deen. Please advise me.
Such conditions are generally caused by two actions; misuse of the eyes (casting lustful glances, watching movies, etc) and consuming things that are doubtful.
Misusing the eyes is one of the things that are most destructive for the soul. It deprives one of finding any pleasure and happiness in good actions. Instead, one will only feel attracted to things that are haraam.
Consuming things that are doubtful also has a similar effect. You should think carefully as to whether you have acquired any doubtful income or consumed any doubtful food. Perhaps you took or used something without the owner’s permission.
Ponder as to which of these two actions apply to you and immediately make amends.
