"I didn't think it was my job to accept what everyone said I was and who I should be."

You are allowed to grow, to change, to make mistakes.
You don't have to be who people think or say you are.
In life shit happens.
There's shirts and bumper stickers that say this for a reason. Things happen, sometimes it is or isn't in our control or our fault.
Illness, change, mistakes, accidents and just life in general will happen.
What is amazing is the perspective that comes from shit happening. Suddenly you are aware of the things in your life that are truly important to you.
Be it family, relationships, career, or whatever you value will suddenly become very clear to you.

Take these opportunities to learn, to grow, to change. Take a clearer look at what is in front of you. Make the changes you need to make if you don't like what you see when you look inside.
Some people won't like those changes. Most people hate change. It's uncomfortable. People don't like discomfort.
Take time to focus on self improvement.

Don't let other people write your story.
