I feel where you're coming from. I'm definitely tons (and tons) fatter, I want to sleep a lot more (escaping from work I think), I feel stupider than ever before - even more so than when I worked in a nursing home when I was 16 and was treated like a idiot - and I feel as if I barely have any friends left, I never get to see them. Starting to feel the slope into a depression and trying to get a handle on it. :-(
In my final year and it's been up and down since the start. It hasn't always been this bad (although the feeling stupid thing kicked in from day 1) so hoping that this is just a dip. It's amazing how the end seems in sight one day and then totally disappears the next!
Thanks to everyone else on here for sharing, obviously I really hope it gets better for everyone (sending out what good thoughts I can currently muster) but it makes me feel better that it's not just me! :-)
