First of all where do you get your facts that ‘Teenage years are the most crucial years in a person’s life’. Being a teenager is a stepping stone to your future. It doesn’t determine what groups someone will enter, who they will be and it most definitely doesn’t determine how successful someone will be. Sure some habits that are picked up while in high school aren’t always the best but they can help you make your life better. No one lives a perfect life with no mistakes. Everyone has something they want to hide or wishes would disappear, some are just more intense than others.
Second you really have nothing to back up you statements. I mean I know my parents can be very protective but they are not the only reasons I have had problems with my body. I have matured now but there was a time when I thought I needed to be perfect for people like you. I was not happy with my parents because I wasn’t happy with myself and who I was becoming. This is a two way street. You have to have respect for your parents before they can respect you.
Thirdly if you’re not ready to be pregnant then don’t have sex. It’s as simple as that. There is no “well it’s safer with protection.” No it’s not you are still introduced to STDs and a chance of getting pregnant.
And lastly. Ya every teenager is an emotional roller coaster but the disorders you listed like bipolar, autism, depression, and anxiety are inherited. They run in the family. Autism is not something just pick up while going to school you are born with it. Some teenager have more health issues because they spend too much time thinking about their health. Your future can change by just one look at something. Your action now can affect them but they can NOT define your future.
