This response right here is exactly why the term "toxic masculinity" exists and why so many young men like Ty grow up to be perpetually angry. Because people like you think that someone his age is supposed to get over it, not be allowed to grieve, not be allowed to process it, and has to just suck it up, "toughen up," bottle it up and have no emotions. Because a VERY large segment of our society thinks men aren't allowed to cry, aren't allowed to process sadness, that we're supposed to be "tough" and are expected to just brush off tragedy and trauma, to just hold it in and keep grinding.
As someone who deals with depression, has lost a parent suddenly and unexpectedly, has lost multiple close relatives in a very short period of time, has lost close friends to COVID, all society has done with their unrealistic expectations is made me into a bitter, angry person.
Any psychiatrist in the world will tell you that bottling up emotions and not processing things are the worst things you can do.
