I don't remember the thread I might have mentioned this. But I stated that I went to group therapy for depression, one of the guys was older like Mr. Rogers old. He had children and grandchildren, still married, did well financially, and was highly admired at his job and would be retiring soon. The fact that he was sitting in the same room with me just made me think that for some people things might never get better in regards to their mental health. I just thought about how I better off myself sooner than later.
I'm pretty sure my therapist put the group together because it was very diverse and she figured it'd be a good idea to see that everyone could be experiencing depression and that no one is immune. It was basically a group of opposite stereotypes. There was a girl that was like a pretty insta influencer type, a soft-spoken kinda plain conservative girl, and me that gave off a kinda rocker party tomboy type with tattoos. Others in the group were a washed-up musician, the old Mr. Rogers guy, a younger wealthy guy who was decent looking, an older guy who was physical ill and had a nurse just outside the room, and middle-aged woman that gave off hippie "Karen" vibes.
So basically, nothing can make you immune or guarantee your happiness. There are things that might lighten or increase the weight of pain you hold. But don't let it make you feel guilty if other peoples standards for happiness don't make you happy.
