Your attachment is normal, her boundaries are not. This sounds really concerning to me: the frequency with which you see each other, shopping, eating out together, significant physical affection... This definitely crosses the line of appropriate client-therapist interaction.

Whatever your diagnosis or your issues, you need a therapist who is your therapist not your friend. She is using you to feel loved, to handle her loneliness, to feel popular, to feel like a good T or to fulfil some other need that is not a client's job to fulfil. It's increasing your dependence on an unhealthy, unstable person who isn't strong enough to hold you and who isn't helping you learn to form healthy relationships with others. I don't think she's intentionally trying to hurt you, she probably likes you a great deal but her lack of skill will end up hurting you.

If you need to verify this with someone authoritative, you can (anonymously) call her professional association/licensing body and describe to them what you have described here and ask them whether this behaviour falls within their code of professional conduct.
