My parents were very neglectful, specially during my puberty!
They let me develop gynecomastia early on (12yo), and never gave me a solution (not even a doctor consultation), my father would even make jokes about it from time to time! It took me years to realize, on my own, it was something that only a very expensive surgery would fix, since medication only works on early stages (first 3 months) of gynecomastia!
I truly needed braces, huge overbite since 9yo, they've only paid for braces when I was 16 to17yo and could not even sleep properly, too late to fully develop my lower third, because of that I needed orthognathic surgery to complete the treatment, but they refused it!
I had a lot of acne on my face since 12yo, I could only afford accutane treatment when I was 22yo, too late, acne scars everywhere on my face and on my back and rear deltoids, once again, my parents always told me it would go away and ''no need to worry, just stop eating this and that''...Well, the acne destroyed my facial skin, then, once again, as an adult, I've paid for two laser resurfacing procedures, but my facial skin is still not good and probably will never be good!
They could have afforded those treatments, but my father would only spend money on cars, my mom was always complaining that I was bringing female problems to them... they didn't care about any of these, to them it was something that only women should be complaining, men are just men, powerhouses, ''just go out there, act manly, and you can fuck as many girls as you want''!
Well, no woman gave me a second look, and because of bad parenting I'm doomed for life as an oldcel now!
