Men above 30 who had extremely traumatic lives pls answer

I am a 19m , things started becoming really bad since last year and ik are going to be worse in upcoming years . There is only hope after 4 years if God wants . I will not waste time by telling my story cause it won't help anyone. In the last year this trauama shaped me into a new person who can do anything which I was afraid of earlier like things which I was afraid or wasn't comfortable I can do them now by saying I am not gonna be dead by this so let's ball . But my mental health which is at its lowest due to all this which has affected my relationships in a really bad way . Wanted to ask 30+ guys who had such a traumatic lives like being unemployed and unloved for year or loosing your only child to accident etc . How the trauma and falling mental health shaped you over the years and do you miss the older one or is this better.
