I went through the same thing except I quit my job almost 4 years ago. What I will say is that ups and downs are part of the startup. The success of most startups and businesses is determined how much the founders are willing to endure until they find that secret formula, but in most cases it wont come over night.
Many of my friends have startups that looked like they were done, but turned into great successes.
If I were you I'd do the following:
1. Look at your traffic sources where was your traffic coming from before?
2. Audit your product to understand if there are things you can do to bring previous visitors back, and bring their friends with them (social integration).
3. Look for other opportunities to monetize. If you're strapped for cash look for other ways to make money like consulting gigs.
Realistically you are just getting started, so if you have it in you just keep pushing/learning/iterating.
