I think you will find that certain people are predisposed to Roscaea (the exception being certain drugs which can actually cause Rosacea).
If you would like to think of Rosacea like a large boulder just balancing atop a very high hill.
There are external factors like light winds and showers (equivilent to low grade stress, sun/heat damage, reaction to irritants etc) which exert a force on this boulder. These forces may not be enough to move it initially, but one day when a cyclone or a tidal wave hits this boulder is forced out of equilibrium and the process starts.
If the external factors continue to cummilate the slope of the hill increases and the boulder picks up speed. If the external factors are reduced, so is the speed of this boulder. The faster the boulder is going the more momentum it has behind it and the longer the neccesary duration of trigger avoidance is needed to slow it down.
Although this boulder can never be removed it can be slowed down for extended periods of time which are usually just as good.
The best thing to do is to try and keep it at rest . If this fails then the only option is to slow it down.
In my case my Rosacea progressed from one really bad sunburn. In your case it seems to have been triggered by stress.
On a different note, there are rules and regulations in Australia governing the dismissal of an individual from paid work. One of these rules is that the employee must be clearly be made aware of the (lawfull) reason(s) which lead to there dismissal.
Social phobias can be very difficult to overcome, particularily in there developed stages. You seem very keen and willing to get through yours and seem to have made very good progress with the help of your psycologist. Dont let a few bad situations shadow all the good work done so far. Stay strong and move forward. Maybe take another holiday
Hope this clears things up for you.
All the best,
Mike
