Yeah and it is especially hard for high achievers to ask for help or even consider that they should ask for help. I think its completely foreign to them.
Sorry, not trying to be a jerk, but unless there is actual comparative evidence, I don't think one can just assert that high achievers struggle in getting help any more than others.
It should be common knowledge by now, as the problem has been documented for decades and discussed here many times.[1][2][3][4]
As far as an actual citation: "Studies from Kjølseth et al. (2009), and our own findings (Szücs et al., 2020), suggest that older adults who die by suicide or have late-onset (mostly high-medical lethality) suicide attempts are often high-functioning throughout most of their life, and characterized as controlling, rigid, high-achievers, also high on orderliness (a conscientiousness subcomponent)."[5]
