Right now, I would tell you to read Hulda's book. (It is free.) By the way, do you live in the US?
Google Dr. Richard Schulze and study EVERYTHING he says. I do know he would tell you the first thing to do is clean your digestive system. Juice a lot! Garlic is a GREAT antibiotic. Fasting is good, too. It is a great healer. Get lots of sunshine. Walk barefoot in the grass. (It is called earthing.)
The oils that have been suggested are good, but what you need to do right now is work on cleaning your inside.
Have you tried detox baths? Soaking in Epsom Salts will draw out toxins out of your body. You can add whatever you want to these Epsom Salts baths...ginger root, cayenne. etc. Soak as long as you want.
Have you tried enemas? If not, they can be great healers. You can add whatever you want to them. It doesn't just have to be water. Any herb is ok. Believe it or not, coffee enemas are awesome.
One thing I believe is YOU have to take your health into your own hands. Try everything. Some things will work for you. Some things will not work. But, your body will ALWAYS tell you what it needs.
