“I posted here on this forum to seek advice from more actual “grown-ups” with real-world experience in the workforce and life in general.”
I know that “transgender” is a hot exciting topic now, but regardless of the reason, many parents/students/children have differences that stress the relationship. Living at home, politics, drugs, church and faith, marrying the wrong person, dependency in mid-20’s, sex, etc. A lot of families, maybe even every family, experiences stress in relationship between parent and child. This seems more normal than unusual.
Real world and workforce referencing the above quote? Move on and be you. There’s a big difference between mid-teens and mid-twenties. Being you may result in some difficult choices and sacrifices, but plan on those happening for a long time.
