Welcome to the forums.
Sorry to burst your bubble, but I first think your comparison to this journey to a suicide mission is not helpful. I appreciate mentioning support from others, though the value of their endorsement means little if there's nor LOR. It's not good to be flippant about mental health challenges, though I think you were just being a little hyperbolic.
That said, your non-clinical volunteering is unsatisfactory. Founding a non-profit helping others prepare for science competition is leadership extending from your science/academic competencies. It doesn't address service orientation, defined as being in a position to help others with their needs. For non-clinical volunteering, we would look for food distribution, shelter volunteering, job/tax preparation, transportation services, or housing rehabilitation; at minimum you should have 150 hours when you submit your application or you will be screened out at most schools. Seeing that you are also trying for brand-name high-metrics applicant pools, you should have 250 hours minimum to stay in play with your peers who will have more hours than you do. Tutoring, teaching, and mentoring are also academic competency activities that most premeds do, so it doesn't help you stand out.
As described, you have zero service orientation/community service activities, which could undermine your application.
Furthermore, your 150 hours of clinical experience is nice and helps you avoid getting screened out at most schools, but playing in the high-metrics applicant pool makes you an outlier (negatively). Again, I prefer 250 hours by submission, or you won't compare to other applicants who will likely get interviews.
Finally, aren't you a sophomore?
