Should I be honest about my past struggles of depression/addiction with recruiters while explaining the 4 year gap in my resume?

[TL;DR former National quiz champion(covered on TV and newspapers)dropped out of B. Tech in 2020 during peak of addiction and depression . Got over it and sober in Jan'23, resumed college and completed my B. Tech in Feb'24. Picked up coding again and feel ready for a job now Should I be honest or lie about the gap? Been ghosted my few recruiters whom I was honest with.] JS developer here. I used to be a decent student, public speaker and one of the best quizzers in the college scene. Made it to TV shows and featured in newspapers articles. But I never addressed some traumatic events that took place in my life before I turned 16. My depression took refuge in substance abuse and I abandoned all studies/career prospects during the pandemic. Eventually after 7 years of using, I got clean/sober in Jan'23 and resumed my studies. I earned my degree but on paper it took me 8 years to complete a 4 year B. Tech (2016-24). Reasonably I get asked about the gap in my academics by hr/recruiters whom I push my CV to. I've been dead honest to them about my struggles with mental health and addiction in the past. And I've been getting ghosted. (It could be because of skill reasons on my part but I'm not even getting a feedback). Should I not tell recruiters the truth about the gap? Should I leave the addiction bit out? How should I word it? I've never held a real coding job before but been slogging for the last 6 months to get better each day (my github and projects will reflect that). Please help me out with all your valuable suggestions. If you're a tech recruiter let me know how you would perceive my case.
