Hi Sapien, I'm sorry your experience was frustrating. I think she sounds like she maybe doesn't have much empathy. A therapist without empathy would not help me.
I agree, don't be afraid to ask questions and ask for what you need.
I agree with BethRags post, good therapy is a process and works on a conscious and unconscious level. If the appointments are very short though, (20 minutes is short for a therapy appointment) this would make it more difficult (imo)
Counselling is more goal oriented (sometimes)
I think maybe being clear about goals would be a good idea with this therapist?
