Ah Mark,
There is an old saying, no one is an island. Talking to someone might be just what you need. The big problem is getting there. You lead a solitary life out on the farm. You aren't the type to jump in the car and spend hours walking through a city or town, meeting at the local pub, or hang out in crowded places.
First off you can only work on what you want to. Not everything will come out, or at least not immediately. Like anything else you have have trust in your therapist. If they aren't working with you or for you, then move on. You know if you need someone to talk to, the thread is here, and you have me any time you need me.
