The temptations overwhelm me and destroy my psychological well-being. What is the solution?

Among the things that help overcome desires and achieve chastity are: lowering the gaze, frequent fasting, closing the doors to temptation, staying away from everything that incites desire, strengthening one's connection with Allah, seeking refuge in Him, relying on Him, and persistently supplicating Him, along with being keen on the company of the righteous and occupying one's time with beneficial deeds.
