I lost my friend to suicide despite me trying my very best and try and hang out with her and chat with her for hours until after midnight after her first attempt that failed. It devastated me and I had to go to therapy myself because I couldn't bring myself to go out anymore and regretting every day that I didn't try harder or noticed before she tried the first time.
Sometimes you just have to accept some people are too far gone to bring them back, otherwise you fall into it yourself.
