First don't panic. I have had Morgellons for a very long time. It didn't come from clothing or other fabrics.
If you have a mite issue that could be a different problem. Check mite forums and mite specific websites. Some have very good information. Bird mites and other mites are difficult to get rid of but with persistence it can be done.
Fungus is another issue that may be affecting you. Once again check out fungus and how to get rid of it.
