I know this approach doesn't work for everyone, but what I do to help with worry is ask myself if there is anything I can do to change the situation I am worrying about. If the answer is no, then I stop worrying because worrying is only hurting myself and making things worse (increasing anxiety), and I don't want to be the source of my own discomfort. If the answer is yes, that I can do something about the situation, then I take action. Taking action helps me feel better, like I am not so helpless, like I am doing something! If your worry is that you are afraid your T won't come back, it seems the only way to know is to ask her, and you have tried to contact her and she hasn't responded. So you have taken the action you can with this particular worry, which is good. Some people who are religious also feel that something they can do is pray (e.g. that your T is OK), and this helps them feel they have done something too. Unless you can think of some other action to take to find out if she is OK, there is nothing more to be done on this, so try to shift out of worry mode. You have done what you can.

You have also taken action in coping with your T's absence by contacting a hotline, trying to find a backup T, and posting here. These are great actions. It sounds like a backup T can't be found on short notice, but the hotline was available to you. I hope you can continue to use it if you are unable to cope on your own. When your T comes back, could you will ask her for the name of a backup T in case you have a crisis in the future and she is not available?

I think this is a negative overinterpretation/generalization of how the people in your life have responded when you told them of your worry and anxiety about your T. They each tried to tell you something they thought might be helpful. People can be clumsy in their responses--most aren't trained (or naturally good) communicators. When your husband said just wait for her to come back, he may be trying to help reassure you that yes, she will come back. I would encourage you to keep spending time with your H and friends. It doesn't have to be to discuss your T's absence with them necessarily, but just spending time with those to whom we are can help us feel supported and cared about. Bake some cookies with a friend, watch a funny movie with your H and laugh together--these things help us feel loved and valued. Feeling that way can help us when we are anxious.

I think you will feel reassured once you meet with your T again and see that she hasn't changed, experience her empathy and caring face to face, etc. For now you can't get that direct reassurance, so hang in there until you see her again.
