Should I stop consulting the doctor and taking the medications that have improved my psychological state, and what about the benefits I have gained from using computers and the internet, knowing that I previously used pirated software, and was affected by the fatwas boycotting American products?

Obsessive-compulsive disorder is an illness like any other and must be treated. Using a computer and the internet for scientific benefit is permissible in Islamic law. Even if you used pirated software due to your ignorance of the ruling, the prohibition is restricted to the buying and selling of pirated discs, not to their personal use for benefit.
