On the Antibodies, I also believe they have a much greater impact on the rest of the body and not just the Thyroid, there are TSH recepters scattered all through out the body tissues which are all prone to excessive stimulation from the antibodies. In addition to that you probably have other hormonal imbalances due to the Graves disease and these will contribute to moods & perceptions.
Regarding anxiety issues, these may be enhanced by the GD, and may even have been triggered by the GD, but they can often run their own course, so have a look at some tools to help you manage the anxiety. One individual I know had GD & Anxiety come on at the same time, after 18 months on meds the GD tapered away and hormones were all normal, but Anxiety was as strong as ever. Then she found some management strategies and anxiety subdued within a week, it was not hormonal in her case it was behavioural and she just needed to break that pattern. It comes in all weird shapes and sizes, one guy I read about had 6pm Sunday evening anxiety, he would be fine all week, come Sunday he would think will it happen, by mid afternoon he would be a bit apprehensive and then like clock work he would get his 6:00pm attack, something happened one day and he got stuck in that rut, plenty of others experiences out there if you just search “Anxiety Attack”, "Morning Anxiety seems to be a big one.
On the personal issue, as said don't jump at shadows, stick to the facts of what you know and don't try to join the dots and add 1+1 to = 5. Be strong in yourself, build your confidance, no matter what the future holds you will be in a better place if you are true to yourself.
