The worst thing you can do to recover from illness is to dwell upon it. To ponder, "Perhaps I would be better off with this remedy or with that: perhaps I should read up on what happens to people with this sort of thing: perhaps my doctor doesn't know what he's talking about and I'm going to get worse instead of better: perhaps..."
Find a good, caring doctor and follow his advice. Remove your mind from the illness and trust in the One Healer of all creatures, that He will send His healing energy through this doctor. Be confident you will be healed.
And then let your mind rest on good and healthy thoughts that have direction and purpose to them.
