Hi Michelle,
Wow, I'm proud of you, you're coping really well with being back at work! I think I know what you mean. I haven't had a really full blown attack for some time, either, but it's always there at the back of my mind in trigger situations. If 10 is a full attack then I often get up to 7 or 8 in such situations.
What I'm trying at the moment is the 'come and get me' approach, just showing no respect at all to my anxiety. I just try to think 'So what if I die? Ok, you're trying to kill me, go on then, I'll help you.' Does this make sense? It's hard to explain really, and it's really scarey. It feels a bit like not showing respect to yourself. I'm nowhere near achieving it and I don't feel comfortable with it, but I think it's the way to go.
Don't know if this is any help to you. Good luck anyway, you're doing great!
Marianne
