I feel you brother, or sister, or however else you may with to be addressed. I too have lost a close friend to suicide in 2021. I tried my best to help him, to acompany him, to visit him, to be by his side.. but nothing could do it. I am also pro choice but of course, it will hurt, and I know you're hurting, I know it so, so very well.
Sometimes I find solace in knowing that my dear friend is no longer suffering, and I try to focus on that to move on with life, but other time I just go into denial, hoping he may have been arrested under weed distribution charges or something, and that he is actually okay. I guess I am lucky in having the benefit of the doubt, or maybe unlucky due to the uncertainty, I don't know. All I knew was that he was suicidal to an extreme level for almost the entire time I knew him, and the last message he sent me was happy birthday.
It's been quite a few years and sometimes it still kills me too. I guess the only thing we can do is just.. somehow.. find a way to make peace.. you know.. I am still on that journey myself to be frank.
