> I'm getting pretty nervous

Don't let leaks make you nervous. It's worth presuming your account info will be leaked at some later date, and there are precautions you can take to dampen the blow it has on you. For example, use prepaid credit cards instead of bank-issued ones. That way if your CC ends up on some underground carder forum, it has $0.00 in the balance (and the card can't have a negative balance). Services like privacy.com offer these.

Use burner phones, disposable email addresses. Always poison the well with fake names. Never give out your real name to any service, even if the service demands it. Religiously use Tor for any sensitive topics (Like politics, health). Religiously use DuckDuckGo.
