Therapy can feel vulnerable. You share thoughts and feelings and you allow another person in. You come with your stuff, try to make sense of it, and hope this professional can help you.
Fairly often I hear or observe, even if unspoken, the notion from patients: "but...I'm the exception." As humans with limitations, our sense of ourselves fluctuates. Faced with our own vulnerabilities, our "not enough" often arises. This can be good information, if we can observe it happening with compassionate detachment. Often, though, it is what we are telling ourselves that really affects how we see ourselves and others and can get in the way of moving forward.
You are the exception, actually, because you are, well... YOU - a unique individual with unique tastes, personality and relationships. Being an exception is more than ok, because your path of healing will also be unique to you. Trauma and other difficult experiences or characteristics does not mean you cannot be on your path towards wholeness. There is always hope.
