Great piece.
I remember how rejection felt and it sucked. Having a place to vent and share my story was so cathartic and helped me keep my sanity. I was grateful for the people who let me be sad and cry in front of them. I was mentally shattered at times.
I hate that it's been this way for you, but, Sam, you're doing all you can and you're enough. Wishing you better success, and that you'll look back on this post from the position of hired and see your growth and be fueled to go further because you will only prove it more to the haters. I know that you'll prove them wrong.
