I just thought I'd come back with a quick update.
I went to see my GP today, she was great, we did a depression questionnaire which I answered quite frankly and suggested I was quite severly depressed, which I think surprised both me and her a bit, but I can see when looking at the symptoms like irratability and failure to concentrate. I have been prescribed prozac and offered counselling. I've not been signed off at the moment, but if I feel I need to be I can call her. I think that's ok as work is improving, but in some ways I wish she had made the decision, I'm sick of making decisions all the time.
I've also had some good honest chats with my boss, DH and best friend which I feel better for. So overall I think things are moving positively. I have discussed a few things with my boss to make my life easier, so we'll see how that goes.
I've one question about therapy if anyone can help. I've got two choices, I can see a chartered psychologist face to face through my private healthcare. Or I can use "talking therapies" which is likely to be on-line CBT throught the NHS, I've no idea about the differences or benefits and drawbacks of either. Again, someone just make the decision for me. Any advice or recommendations.
