That was exactly my point with all this.
While the MC cries about some little cut on his finger, people with real trauma(like loosing an arm for example) deal with it better and see thing proportionally.
It's not being depressed, it's called being spoiled and entitled.
There's nothing relevant you can say about whether someone else's trauma is 'real' or meaningful (even if they're a fictional character). If something has an effect on an individual it is real for them because it derails or stagnates their life. Shaming other people's experiences of what constitutes 'real' trauma based on your own belief system is entitled, as is deciding how much resilience should be a base requisite for each individual. Life isn't an RPG where you get to roll character stats. No one starts life with skills, everyone has their own mountains to climb, and they develop their own coping mechanisms.
Stories teach empathy, to see the world through different perspectives. It is how we learn to relate to people whose experience is different from our own. We can't judge what someone else is going through (because emotional and mental states are hidden like an iceberg), only understand the meaning and relevance to the person experiencing those circumstances, whatever their conclusions or reactions will be.
Resilience comes from surviving events and understanding why they happened. In this story we still have no understanding of why, and that is a signficant part of the MC's trauma. We still don't even know the full extent of what happened to him, so it is impossible to even guess why. Currently, he has to decide whether or not to move on without reconciliation, without closure.
This is primarily a story about the MC developing the resilience to move forward and character building; he hasn't yet found his strength. If you are offended by a character learning to socialise and develop resilience, there's plenty of other stories to go around with different plots that you might find more relevant.
