How can I overcome the feelings of guilt, shame, and depression resulting from being a victim of sodomy when I was thirteen years old, especially with my continuous attempts to improve my relationship with my parents?

Sodomy is a grave crime and a major sin among the greatest of sins. If you were not accountable (mukallaf) when you committed it, then there is no sin upon you. If you were accountable and have repented, then this remorse is a sign of sincere repentance. You must be cautious of despairing from God's mercy. Have a good opinion of your Lord and strive for uprightness. Struggle to repel whispers (waswas) and resume your life, and use the computer for good, such as acquiring beneficial knowledge and cooperating in righteousness and piety, and beware of malicious websites.
