$1k bootstrapping for AI app, but waitlist blew up. Please help.

I’m a grad student and this is my first ever app. I turned my PhD research on procrastination into an AI app where you talk to Pebbles (a little character), and it matches your reason for procrastinating (fear of failure, overwhelm, boredom, etc.) to interventions backed by 100+ research papers.

Here’s the thing: A VC told me not to raise until I had traction. So I bootstrapped. Full transparency: I could only scrounge up $1,000 for AI compute before I’d have to start charging. That felt safe… until 700 people joined the waitlist. And now I launch in 2 days (Sept 15).

I keep spiraling on the what-ifs. Like… what if people actually use it and burn through the budget on day one? I’ve already told the community it’ll be free until I run out of bootstrapped $, but I don’t even have a plan for what happens after. I don’t know pricing, I don’t know financing - I’ve never done this before.

I know it’s a “good problem,” but I’m honestly terrified. What do I do???
