kimss,
No doubt this is and will be a difficult decision for you, my wish for you is strength and guidance. My hope for you is to find other outlets to give you that "rush" without being left under a financial burden. New activites and ideas could open up new possibilites and new friends! Though I will miss your posts I will certainly be happy for you knowing you have moved on to another chapter of your life.
Best wishes in your endeavors and I hope you have a wonderful holiday and the best New Year ever!
