Veggy,
It's understandable that you are not sleeping well, especially with the stuff going on with your ex. I'm sorry that you are not getting the right questions asked in your T.
Perhaps you can take an internet questionairre to see if you have any other symptoms of depression, that's how I came to be in the place I'm at. I did it over the internet and then realized I was depressed. Relationship troubles and concerns can sure beat a person down, I hope that you can work things out with your ex.
