I'm half way through now time-wise but it doesn't feel like it outputs wise. Despite often enjoying the research process at the moment it feels like a massive uphill struggle and one which fills me with fear. I'm waking up anxious, can't sleep and feel tired and lacking of motivation during the day. It feels like I've got a plethora of literature and data and yet I don't know how to make progress. I've finally got a bit of structure for my writing, but I can't seem to organise my literature and notes so that it's easy to draw upon. I use endnote, and keep a research diary, but still it feels like I'm swamped and without direction. Any tips anyone?
