This is a fantastically ridiculously comment.
> my assumption was that suicidal thoughts originate from one's own brain and way of thinking - adjust that and these issues would go away. Unfortunately, while this can work (for me it worked extremely well, though I should also say, I don't have suicidal thoughts to begin with
You're, in this comment and the part I quoted, saying that adjusting your thinking worked well for you (with the implication that it worked well in dealing with suicidal thoughts), but you say you don't have the problem (suicidal thoughts or ideation) under discussion. This is like saying, "I've heard that you can walk it off when you break your leg, and that's worked for me, but I've never actually had a broken leg." Complete nonsense.
> but you say you don't have the problem
I think it's very clear stated that they HAD the problem, but were able to work through it, resulting them in not HAVING the problem.
So, it's more like they broke their leg, it healed, and now they no longer have a broken leg.
edit: I am dumb.
