@FeraLune My advice would be to reflect on what you have done, what you would've done if you could do it again and what you will do moving forward. Essentially treat everything as a learning experience and an opportunity to grow!
i know what its like to get doors slammed shut in my face. i know what its like to hit rock bottom and feel like you will never make it out. don't ever give up. dont ever stop. keep on trying. the path to your dream might not be the path you envisioned but you can make your own.
