Through-hole soldering issue
The Solder pads that you lost connect to traces. You probably will be able to see them. Scratch the surface (solder mask) of these traces and connect anything you want on those traces

Do not scratch too much, or you will remove the trace as well!. Removing the solder mask enough to see the copper like the image above is enough. Then clean the scratched area (with isopropanol) and solder on there. (If you do not have isopropanol use alcohol, but quickly dry it out as alcohol might not be 100% clean
