Willowleaf, I'm sorry you're struggling with the attachment. I find it very hard too, but am lucky my therapist makes her self extraordinarily available to me, although it can backfire and make the attachment issues even more intense when she isn't available for any span of time.

May I suggest that you ask your therapist what to do with these feelings, how to cope between sessions, how to cope in her absence? I'm sure she doesn't want you in pain. Perhaps she would write you a nice reassuring letter to hold onto in the interim? Perhaps you two can work on some self-mothering techniques to ease things just a little. My therapist has sent me song links, one to a lullaby, and a photo of her garden, and a set of bedtime stories for adults. I've also saved some of the recordings of our sessions (we do chat sessions online) in a document, the reassuring bits, to reread when I need comfort. My final suggestion is to print your post here and give it to her. I've gotten this advice before and found it very helpful. Take care!!!
