I'm currently on this path, been developing/designing for the last year and a half, and will be launching my product relatively soon.

The issue I've been facing lately is self doubt. There's definitely a market, it solves a problem for that market and myself, and the product has shaped up to be something that I can be proud of and share/help with others. But there's this nagging contrasting feeling that's hard to describe, that could very well be fear of the unknown.

What's your experience been like developing a product that solves a problem ypu faced? What was your journey leading up to its release? How'd things work out after release?
