Books on controlling sexual temptation(nofap), food cravings, and temptation to scroll on social media. Just overall being productive and having power over your mind, temptations, urges, and intrusive thoughts.

Im a 2nd year college student and have had a bicep injury for the past year since then I fell into a depression, wacking off every couple days, no food control, and not being productive in school. Tried running but instead I got chased and attacked by a dog causing me to be scared to go outside, dont socialize, dont drive that often. Just all around fell off in the span of a year and I wanna get back into being good since im now taking steps to heal from a bicep injury and visiting doctors.
