'Lost' is a reasonable diagnosis on its own. Depression takes many forms, but in such a situation is when you cannot bring yourself to face working again (been there). Sounds like you've fallen out of the rhythm of work. In ways, you should count yourself lucky - very few people could afford to take 18 months off work without becoming homeless, so well done with this product you created! Have you learned anything on your time off? Something you could use towards developing a v2.0? You could contact those 10,000 people for feedback on your initial product, see if there are any issues.
