The first thing to realise here is that sometimes you are going to be flat out wrong in your assessment of your doctor/therapist and his/her's motives. You won't always be able to determine when your doctor is being aggressive, uncaring, (name your bitch here) and when he/she is pushing you to explore some part of you you'd rather not look at. Solution??? Not any clearcut ones, but if you are feeling under attack a bit, before you run and hide, get some guts about you and say something like the following to your therp. "Look, I'm feeling angry and threatened by your approach. Are you aware of your tone and is there a reason for it?" There's a good chance that eliciting an assertive response was exactly what your doctor was hoping for..or maybe he/she's had a crappy day and will say so...the point is, open your yap and hold your ground. There is absolutely nothing to be gained from silent suffering. All you end up with is two people who misunderstand each other's agendas.
The other common problem, besides a mismatch in personality mentioned above, has to do with what I call the therapeutic stalemate, You've been with your therp/pdoc for awhile; you've beaten all your personal demons to death; and now it's all a rehash of the same old garbage that just doesn't seem relevant to you anymore. So what are your options at this juncture? And how did you two get in this sorry mess anyhow? No mysteries here. Your therp and you have become the quintessential old married couple: comfortable with one another, but bored to death with covering the same old topics. The answer isn't to manufacture a problem to talk about, it is instead to:
reevaluate the necessity of ongoing regular therapy, (maybe a phone check-in once a month or so will suffice)
make all old topics verboten unless you the client bring them up,
decide to talk about anything except the same old "problems." Music, art, hobbies, kids, school, crappy neighbors, his bad hairdo, her recently-acquired puppy. It doesn't matter what you discuss, troubled spots have a habit of finding their way to the forefront of a conversation and it won't matter if you were originally talking about the dentist appointment you just had or your kid's new teacher.. Besides, part of what a good therapist does as you and he/she chat is observe your general demeanor, including body language, speech pattern, animation and agitation, all of which can best be done when you are at ease with a current topic. And finally.....
The goal of therapy is supposedly to get you over the roughest spots and able to cope for the most part on your own. It is entirely possible that goal has been achieved, at least for the time being. In which case it is time to change the relationship to that of med-manager/med-taker which may require nothing more than necessary monitoring tests like lithium serum readings. Many therapists will not tell you that you don't need them anymore. To them, a sign that you are ready for less intervention on their part is your ability to flat tell them so. So if you genuinely think you need less therapy, then by all means tell your pdoc/therp that is the case.
