I think most of my friends see suicide as "weakness, not being strong enough" etc. I'm not sharing my thoughts with them about this nor my issues. Maybe it would help to be open with them and they might get a different perspective but I am unable to face their criticism lately.
Yeah, it's hard to imagine something you haven't experienced, but how hard it is to be open minded and accept whatever the other person is going through as valid?
My ex-boyfriend shared the same opinion, we used to have fights about this.
