ate poorly and started purging in early adolescence

I started before i was even a teenager. I would constantly skip meals and vomit the things i ate. I had no idea what i was doing that time so i kept on doing it for months even for a year. My mom told me she heard a real life story of a son always dumping his food away without his parents knowing it for years and he ended up being short as 5 foot 2 being an adult and commited suicide later on. Im 5 foot 2 turning 14 in 5 months my mom is same height as me and dad is 5 foot 9. When was 11 I did a growth test and it showed my future height would be between 5 foot 7 and 5 foot 8. My parents were in shock because of this they kept trying to convince me to take hgh shots and they would fight a lot about it. I havent told this to my parents but I am back to eating healthy and trying my best to fix my mistake for the past month. My parents would always say if i cant be as tall as my dad then my life would be depressing. I want to start taking hgh shots starting from now to recover my lost growth potential and possibly get a little taller than my adult height but its hard to decide if it is really worth it. i need help
