Hi anxious girl. Honestly to me it seems the real problem is with your relationship with your therapist. If you don't feel comfortable showing your feelings or telling her the truth about your feelings it means you dont yet feel fully comfortable with your T in general.

How long have you been seeing her? It maybe that just not enough time has passed for you to feel comfortable with showing your emotions to her yet. It could also be her personality is just such that it's hard for you to open up.

I don't think you should stop. But you may be moving too fast. You may need to give it more time to develop a relationship with this T and trust her. If it's her personality that you feel is preventing you from showing your feelings then perhaps you could look into seeing a different T.

Just my thoughts. You definitally can do this :-) keep trying.
