You are litterally one of the best writers here. I KNOW a ton of people here would be seriously heart-broken if you left, and I would be one of them. I can't believe someone like you, {{Damn girl, the majority of your stories green. GREEN!}}, actually loses confidence with stories like yours.
But we are human anyway. I think.... If doing this doesn't make you happy anymore, no one can stop you if you leave. I would want you to leave if this makes you sad, or unhappy in any way.
Happiness keeps guys like us going; and let's face it; you make shitloads of people everytime you update one of your stories. I know the virus really fucks with the website. And if you feel like you don't want to keep going, that's fine.
Just do what you want to do. That's all that matters. I'll back you up if you decide to leave. And if you you stay, you'll make me; along with the, i don't know, thousands of people who read your stories, extremely, unimaginably happy. Either way, just go with it.
Be happy.
