I know this gets said on here a lot but the best thing you can do is to tell your T how you feel. I think you should tell her all of these feelings. You have 3 sessions left with her so you should say everything you need to so that when you leave at the last session you don't leave anything hanging for 5 months. You could write it all down and give it to her or read it to her or you could write her a letter and give it her. I know this is not easy for you so the best thing might be to say whatever you need to so you don't have any regrets.

It was very hard for me to tell my T about my attachment and how I envy her and my transference. It was rewarding to talk about it and I felt much better after getting it all out and seeing that she still accepts me no matter what. You are not wrong for how you feel. Attachment to a T is normal. Feelings are not right or wrong, they just are. I hope you can share all of this with your T and you can feel somewhat better. You could ask her how she feels about hugs and see what she says that way you are not directly asking for one. If she says she is fine with them you could ask for a hug at your last session before her break. I am pulling for you and I hope you can find some peace with this difficult situation.
