It's still no harm to contact a career guidance counsiller. I mentioned I had gone from Nursing to Progaramming - well I spoke to this guy Erik Guiry - he was fantastic, and I have always recomended him to friends, am not sure if he is still doing it..
A girl I went to collage with and later worked with (I was a mature student as was she) - had done radiography and computer applications, and she hated programming with a passion!
I suggested she speak to this guy, she did and he told her that she had three D vision!! That if she had her life again she should have done architecture, but he would not recomend that she do so now! She has very successfully gone in to property development in the UK...
