How can one get rid of the addiction to viewing forbidden images, deal with the continuous feeling of guilt and the memory of past sins, the fear of Allah’s punishment in family life, and the feeling of not being successful in life, knowing that good deeds do not alleviate the feeling of despair from Allah’s forgiveness and people’s negative expectations towards the repentant?

The gist of the answer: Mend what is between you and Allah, and Allah will mend what is between you and the people. So, be patient with what has befallen you on the path of your repentance, and know that remembering sins leads to increasing good deeds, not to despair. For Allah forgives all sins, and repentance, turning to Him, patience, and steadfastness are the solution. Combine the fear of your sins with hope in Allah’s mercy. The lack of success in your life might be a consequence of sins, but sincere repentance erases that, and "no bearer of burdens will bear the burden of another." As for people’s ill-treatment and their remembering your past, it is against Islamic law, for those who repent from sins are your brothers in faith, and abandoning disobedient people has its regulations.
