Selling personal items on eBay

Hi. I buy and sell a lot on eBay. The items are jewelry, shoes, handbags and clothing. All of them were purchased for personal use and sold for less than what I paid when I wanted to buy something new. The amount is over the $5,000 eBay threshold for reporting. Will I have to pay income taxes on items that were sold for less than I paid? 

Thank you for your help.
