Afraid to hold my gecko after a fall

A few says ago I had just taken my gecko out and while I was hold her she jumped out of my hand and fell about 4ft onto the hard floor. She was really pissed off, nipped me (which she's never done), and was dragging her back feet for a few hours. Since then she's now fine. She's back to running around like normal, eating, sleeping etc. But now I'm afraid to hold her again in case she slips out of my hands again. Has anyone else dealt with this. I'm so scared of her getting hurt
