Dealing with chronic illness is something that I have had to deal with for 4 years too.
My understanding is that our bodies start by giving us little subtle clues that something is wrong, however in our culture we ignore these little niggles or supress them with western medication. Eventually the signals get stronger and stronger and we continue to cover them up with drugs, fail to change our diet or attend to our emotional needs. Then finally the system starts to collapse and we say 'why me?'
I had a lot of alternative treatments but wasn't getting well. Eventually I realised I wanted someone to 'fix' me without me having to do anything. I have now had to change my diet, my attitudes, deal with a lot of emotional stress I was storing, reconnect with my spirituality - but the biggest thing I did was a physical detox as i had colon problems. Suddenly I starting releasing emotions that I didn't even know I had!
Yes sometimes I'd look at my friends that still drink and smoke and think it wasn't fair, but you know what, my best friend has just been told she is on the way to developing an ulcer if she doesn't change her lifestyle. It catches up on everyone eventually. I know see my illness has been a wonderful opportunity to turn my life around. I would have never learned how to heal others if I hadn't been ill myself.
