Hi and welcome to beyond blue.
It is a big step to recognise a problem and then looking for some sort of resolution.
You have mentioned a few issues in your post - isolation, alone, invisible, etc.
To you, if you did have a job, would that stop the other feelings you have?
Or I guess I am asking what issue is most important to you?
I am interested in hearing more of your story and then perhaps together you might find some way forward.
