Nancy Wilder, you seem to have some issues with minerals in your water that build up inside your faucet :-). The repairs are not really that complicated but can be tedious. Most leaky compression faucets will need new seat washers. Pry off the decorative cap on the handle, remove the handle screw, pull off the handle and use a crescent wrench to unscrew the packing nut. After unscrewing the stem, remove and replace the seat washer held in place by a brass screw. Always make sure that you cut the water supply to the faucet before taking it apart. Each faucet can be a bit different, so images of your particular once will be helpful. Post images of your faucet with your question. Use this guide for that. Here is a decent video about the repair as well.
