I know how you feel, when I was home I felt alone and isolated and wanted to get back to wrok so very much, when the time came I was scared. I was so afraid I would no longer have it in me, that my chemo brain would surface and make me look foolish, but I was back here about 30 minutes and I realised that was silly, that I did have it and that I was the only person judging me.
Its great to be back with your peers, to have a sense of purose and have normalacy in your life again, though believe me you will get sick of telling your story, its all well meaning but thats the most tiresome part of returning to work.
Good luck.
