Inny,
This is not a bad thing. Most mental illnesses are biochemical in nature, as far as I'm concerned. It's our genetic makeup combined with our life experience that provides our feeling state. Maybe this is good news, as you can have an evaluation with a p-doc and maybe get some meds to help you feel better. I remember when my t first suggested anti depressants and I was a little worried about using meds. Now I am glad he took the initiative. go with the flow and do what feels right. Good luck.
