I think you may be projecting, because you are acting a bit like a keyboard warrior — telling others to see therapists. Consider that other people have different views, that is all. To some, the cause (principle/life goal) of exploring where others have not gone is enough.
1. Go where others have not gone, with a 50% risk of death.
2. Wait 5 days for temperatures to rise, and go where others have not gone, with a 0.5% risk of death.
Choosing 1 isn't "different views, that is all", it's pretty objectively the wrong choice. It's not dying for a cause, it's not brave, it's not idealistic. It's pointlessly suicidal. So yes, I'm saying if you think 1 is the right choice you should see a therapist.
Notably, NASA requires all astronauts to undergo psychological evaluation, even if they aren't claiming they'll take insane unnecessary risks. So it's not like I'm the only one who thinks talking to someone before you potentially kill yourself is a good idea.
