Often in therapy, as content comes up, there are different paths they can take. There are often many issues at once, relationship problems, environment, job, etc, plus distorted thinking and feelings as a result. Often there is not right/wrong but only an intuition that comes from a good therapist on which direction to go, when to be gentle, when to push a bit.
Generally speaking, therapists are not judgemental people. Most people that go into this field have had many adversities of their own. They are often quite colorful people. It is their ability to relate to various circumstances that lead to this profession. Their empathy can be their best asset and their worst enemy. They do not think you are wasting time-they are patient people. They dont think youre stupid, they think your emotions are interfering with your ability, not lying but having trouble describing, doesnt hate you-trusts you to share at your own pace. etc.
I hope you can be more gentle with yourself in your thoughts about this. When you share with your T, you may discover that this is needed for a starting point of real trust to build, as it would be hard to trust with those messages going on. Once aware, T can help you turn those critical messages to self nurturing ones, and that can be the beginning of some real healing.
