I'm sorry your going though this. I remember a few months ago when I went thru thinking I was going to die, I felt it inside, I was so worried and am a worrier anyway and have had anxiety for years.
I've had dizziness now for almost a year and with this being the symptom that stressed me so much my health anxiety raised it ugly head.
I went to my ENT and asked him if it was anxiety only and he said I'm not going to say that until we do some tests. That worried me because my gut just new I had something that was going to kill me. But as went from doc to doc there was nothing life threatening. Yea my thyroid was out of level but we finally fixed it. I still have the dizziness and boy had it been hard for me. It scares me to death. I don't know why maybe because many disease can cause dizziness. I'm scared to death of disease.
I have had all the things you listed to include that white film look in my vision, which was anxiety, I used to get it in the mornings I would look around a room and it would look almost smokey and gray, it drone me crazy but it has calmed way down and when I have bad and wiry it shows up occasionally. I have the standing and feeling my heart pounding almost every morning and during the evening, thinks it because I have to move around and when I move I get dizziness and feel odd and that scares me so. I've had so many symptoms and it takes a few weeks to go they each one until I finally convince myself it's anxiety again.
The only thing o know they is not all anxiety or maybe it is, is the dizziness. I get it almost everyday is some form or another, whether it be off bajance feeling, falling feeling, rocking swaying feeling, in a fair rise feeling, bouncing floor feeling, sitting down and feeling like I'm moving like a bouy in the water.
I don't know if you've thought about talking to a psychologist but maybe it will help. I'm seeing on and it dies help. There are sine great panic websites also that can explain things well, I read a good book about worry and how the mind causes it, it's called The Worry Trick. I ask so keep a journal of thoughts , do meditation, and have been working in a workbook called, the anxiety & worry workbook.
I really hope you feel better and can calm yourself so you can think better. I know for me Xanax calms me down so I can relax my mind and let me think clearly
Feel better and know your ok, it's the anxiety, it causes an awful spiral
