This post is very timely... There are a lot of people who will say hurtful things, often out of jealousy or a lack of understanding. You're right to keep moving forward and putting your thoughts one word in front of the other. I am glad to hear your experience is molding you and making you into a better writer. You are going places. It takes a lot to share bits and pieces of yourself on the internet. I don't think that it's time wasted. I love this part...

Anger is like a sail, the more you blow into it, the bigger and stronger it gets. As soon as you stop blowing it up and star letting the air out, it gets soft and weak.
