I'm currently undiagnosed ( only diagnosed w depression and anxiety) I've had about 7-8 sessions w my therapist but I'm just starting to trust her. she practices the CBT approach and it doesn't seem to be helping cause she tries to get me to rationalize with my thoughts and keeps asking me what I was thinking or feeling when I got triggered. my answer is always I don't know as it's way too complicated a question to answer and I can't put the feeling into words but she doesn't get it and keeps asking to to find the root causes behind my thoughts and it makes me feel worse. 
also on a side note , my mom talks to her a lot. not only texting her but also speaks to her alone for 5-10 mins after each session and it gets me really paranoid because I feel like they're plotting against me or she's telling my mom things I told her. and it makes it harder for me to open up but she doesn't get it. I want a new therapist but my parents like this one and I don't know what to do.
