I am working a lot on emotions too and learning to better listen to my needs so as to become more healthy.
I have strong earache issues and I keep adressing what it is I do not want to hear.
Your face could be a matter of loosing face... =perception and judgements of others towards you and then you would need to learn how to let go and find the strength in yourself to protect yourself from such judgements.
It could be an issue of containing your 'self.' I do not know how to formulate this, but the skin is the container of the body and the skin irruption would somehow show a weakness it your hability to contain yourself as a person.
THe skin is a protection against the exterior (bacteria and such) and perhaps you need to build better defense against some people parasiting your life.
I just had to mention a few possible tracks to explore your emotional disfunction ( I am heavily involved into exploring mine and I find the book Women Who Run with the Wolves to be quite enlightening.)
