Why not? Noone should feel ashamed of needing a bit of help, if they need it. My mention of it was not a demeaning “go see a therapist, crazy” or anything toxic like that but a suggestion that it’s worth exploring if things are hard to handle.
Suffering is completely normal and a true necessity if you are striving towards any sort of development of “self”.
That will depend on your philosophy and what you define “suffering” to be. Yes, we need challenges and the like in life to give us stimulation and impetus towards self-discovery. However, I would much rather noone have to experience the pain and trauma that I have experienced and try to do my best to support others towards that end. I don’t by into the idea of needing to experience a painful and challenging life to make something of oneself. There’s plenty of people who are successful without experiencing traumatic events. There’s also plenty who are left entirely broken due to their traumas.
