Hi Andy, I sympathies with you - my Father was actually an alcoholic, and with my emit, I walked on egg shells. I cannot remember how I developed my emit, but I wonder, with a little dash of hope, that because it is early on you have a good chance of overcoming your fears.
If your emit started from the media - please dont listen to it! You cannot believe what they say, but I'm sure you know this already next time turn off your t.v/radio if it effects you.
It is unpleasant to be sick, but it is not the end of the world, nor will it harm you. It is not dangerous in anyway. It is only unpleasant and you can deal with unpleasant. All you need to know really is to wash your hands before eating/ preparing food and try not to touch your face.
