After a few days of severe pain, Clarke's family took her back to the hospital.
Clarke and her family learnt she had experienced a traumatic brain injury.
As a result of the accident, Clarke's life has changed dramatically.
She now relies on a walker as she loses balance in her left leg, she now speaks with a serious stutter, and suffers from severe migraines which can make her vomit.
"I would be crying out in pain and nothing will stop."
Clarke said she is also coping with memory loss and her vision "has become worse - everything is fuzzy".
"I have always wanted to help people and make a difference in the community."
She has set herself some goals to reach: she hopes to drive again, walk independently, and get her memory and concentration back "so I can do things like school".
"I think they are achievable goals in the long run," she said.
Clarke said she is still learning, but is finding ways to cope .
"Its like learning all over again."
She says others in similar situations have reached out to her on social media and have been grateful for her openness.
"I have amazing support. I think that is the most important thing.
