Thank you everyone. Well the doc signed me off work for 2 weeks and has prescribed an antidepressant I haven't had before. I decided in my non-existent wisdom to go straight back into work but I ended up breaking down in the office and coming home again. It is impossible for me to take that long off, but I will see how I am tomorrow.
I actually feel quite relieved to have shared it.
And Astro, I hadn't even considered that by taking this I might be breaking my sobriety. I haven't drunk or smoked at all over the last few difficult months, but I need to be able to function at a reasonable level. Taking prescribed drugs isn't relapsing in my very humble opinion.
Thank you all so much x
