Is it normal, that i panicked and sabotaged our relationship?

She believed that dual relationships was perfectly acceptable. It caused me so much stress.

The whole thing or specific parts?

The relationship was with a former therapist. The therapist proposed that she wanted to take on the role of something that I never had. I said yes, but I couldn't handle it. She told me that she cared about me, and it made me panic. (Emotions make me uncomfortable). She was very emotional and I was scared to tell her that I couldn't accept her proposal.
The boundaries of a healthy therapeutic relationship began to go lax. She did and said some things that scared and hurt me. I panicked and sabotaged the relationship without realizing it. Now, I regret what I did.

I'll wait for a year. Then, I'll send her an email. I already wrote a blog post about what I did but, there's a chance that she never saw it. I'm waiting an exact year after I terminated our relationship because, it is usually a year after termination that they say that relationships can form. I don't want a romantic relationship with this person. In the last email she sent me, she misunderstood what I wrote in my last email, and basically told me to leave her alone in what felt like a threatening tone. I'm a little scared.

It wasn't sexual. More like, platonic and business. She wanted to be like a parent to me. She wanted to be an adult who had my best interests in heart. That's pretty much the offer she gave me. However, it got to the point, where it felt like she was crossing boundaries and not respecting me or my wishes.

She was pro-dual relationship. I spent a lot of the relationship fearing when she would pop the offer of friendship on me as well as, worrying that I would say something that would jeopardize that offer.
