Calm down.
Are you a seller?
Did your buyer not pay you?
Your buyer is required to pay promptly or you can start an Unpaid Item Dispute. If the buyer does not pay, the transaction is voided, he gets a UID strike, which makes it harder to buy on eBay. You get your selling fees back, but not your listing fees. He cannot leave feedback or trash your Detailed Seller Ratings.

Did your buyer pay you, but Paypal has not yet released the payment?
As a new seller, your contract with eBay and with Paypal allows them to hold your customer's payment for 21 days against your performance. You are still required to ship within seven days of payment (to PP not to you) to keep your Seller Protections.
The money is held in escrow. PP is not making anything on it.
If you do not ship,if the item is Not Received, if the item is damaged, or if the item is Not As Described, the Hold may last longer while you and the customer correct the problem. This is part of the PP Buyer Protection Program. Do you need help with this?
Do you feed the eBay and Paypal fees are too high?
Well, we all get that feeling from time to time. As a rule of thumb, I allow 20% of the payment for fees. But those could be higher if I were using Reserve, Designer Backgrounds, Sub Title, or any of a dozen paid (and usually useless) options that eBay offers. And the fees for these are never refunded.
However, before you hit the List My Item button, all those fees were stated on the Sell Your Item form. And if you hit the button you agreed to them.
If you need specific information, give us the number of the listing, and we will critique it for you.
