Yessir. I have a close friend in the same boat as me who was born to build a business. He's trying something to keep himself busy while planning the next business. Its taken many months and likely many more. Unless you can spare a few months to deal emotionally with your situation I'd stick to something you were already working on and can distract yourself with without sinking too much hopium into it. I'm trying a mix of old and new projects to keep me mindful.
