Thanks for the response, it's nice to hear I'm not alone! All the best with your recovery.

Weirdly, I feel like I made quite a big step today. I've been feeling more positive the past few days, the depression is becoming less frequent and milder (my best friend made the trip across the country to see me when he heard I wasn't well which I'm sure was a boost) and I suddenly started to feel much 'clearer' this afternoon. Not 100% but much better than I was a week ago. It's nearly half ten at night and writing and looking at the computer screen present no problems! I actually KNOW that I'm getting better now, which itself I believe will speed my recovery. And for the first time in 6 weeks I'm looking forward to tomorrow as a day to enjoy rather than another day to get through. Even if I do go back 'under' tomorrow at least I know I'm moving towards the surface.
