@Sunnyhippy can you make an extra appointment with any therapist of counselor, who would know more about your condition, and be able to offer help? I like all of Layla's ideas, but they are hard to implement when your mind is going 60 to the dozen. I have some short playlists I put in my ear when I am distraught over happenings here at home. Or, comedy tv/movie, something that doesn't require me to think or give input. I'm sure we sound like little buzzing mosquitoes to you, and I wish I could do better!
I seriously don't think that could be staph, but maybe it's worth it to you to take it to the emergency room for them to rule that out? You would be doing something about it, and when they said to you you're fine, you might feel better?
