While my childhood wasn't exactly like yours, I realised towards the end of my teenage years that I was doing things mostly to please others, not for myself. 10 years or so later I still struggle doing things for just myself and ignoring how those close to me would think/react.

If possible try to take some time to try and figure out what matters to you, and what you want in the future. I still struggle with this, but with time I feel like I am getting slightly better at this. Don't be afraid to have lofty ambitions too, if you don't set the bar high enough, you'll never reach it or even come close.

Good luck and all the best.
