What is the remedy for incontinence, and how can a repentant young man overcome the states of psychological collapse, conceit, showing off, hypocrisy, despair, falling into temptations, and abandoning acts of worship that he is experiencing?

We advise you to fear Allah and to repent sincerely from sins, and not to despair of His mercy, for despair and feeling secure from Allah's plan are among the major sins. Adhere to your prayers, avoid disobedience, participate in da'wah (inviting to Islam), read the Qur'an, and keep company with the righteous. Strive to be sincere in your actions, and be mindful of Allah's greatness and that He is aware of you, and that people have no power to harm or benefit you. As for reading in front of the Shaykh, the fear of making mistakes is natural and not a form of showing off (riyaa'), and you should master recitation in all circumstances. To treat سلس المذي (constant pre-seminal fluid discharge), refer to Fatwa no. 77006. Marriage is one of its treatments, and you can consult doctors.
