Hi @adelewand welcome to the forums.
There will be a lot of people on here with anxiety (the most common MH issue in Australia). Of course there is a large variety of symptoms and underlying causes.
Just a tip - the forums are anonymous, so best not to use your name, or anything that identifies you. When you reply to someone put an @ and then their username so they know you’ve replied - the forums are vast.
I also have anxiety among other things like cPTSD. I also have had it for decades. I also have recently had an exacerbation. The loss I have had, pales in comparison to yours, because I just retired. So I have lost the sense of identity I got from my job, as well as the social interactions at work, the routine and the money. And also confidence.
I have always lived on my own (since adulthood) and I don’t have any close supports. So I have got through it with work, sometimes my GP and sometimes a psychologist.
So I think I can understand to some degree how you are feeling.
The forums are a friendly and supportive place and I would not be surprised if there were people with a story more similar to yours than mine.
I hope you can connect to people here
