There's no need to be scared, Kathy. All you need to do is be careful. Learn to recognize what is and what is not a valid PayPal address in the URL box of your browser. Know that PayPal never misspells its own name, never directs you to enter sensitive information "to confirm things" and ALWAYS addresses you by name or business name (however you're registered.) Most importantly - PayPal web addresses (URLs) ALWAYS begin with https://www.paypal.com/... Note the "s" in the address. If it's not there, it's not a valid PayPal address.
Lastly, if you get an email or a web page that states your account is locked/suspended/under investigation/being held for customs/whatever, stop what you are doing, open a completely new browser window. Type in www.paypal.com, log in to your account. If there is no indication of a problem noted after you log in, you can pretty much assume the problem message you got was a fake.
Don't be scared, be proactive, be smarter than would-be thieves.
