Hi,
I think that they all are related to your anxiety. The tightness in the face is most definatley nerves..I have had that. I have read a lot of posts where people have described that as a symptom. When you are under stress you also feel very heavy, like you can barely drag yourself around, had it! Weight loss is common with stress, and depression (unfortunatley, I didn't have that). Vivid dreams are normal when you are anxious...your fears will always show up as bizzarre dreams. I have em all the time when I am stressed. The other night I dreamt my mother moved in and my husband moved out, and I was chained to a kitchen chair?
Something will be different every day, and you will be scared until you realize that you are well, and it is BFS. There are a lot of frightning symptoms..and you are letting anxiety get you. I was in a terrible state of panic when I first hit this board. I needed constant reassurance, thank God that the people here were patient with me, and I got it. You should ask for all the help here that you need, we all want to give it. You are going to get through this, and you are fine!!
Enjoy your day.
