Hi, I have had the same kind of problems in the past. During my degree i had a hospital laboraotry placement. I had to work full time and then find the energy to do massive assignments in my spare time. I found it near immpossible to do work. I suffer from anxiety and sometimes even mild depression, and its often when im at my lowest that i found it most difficult to work. I found that literally forcing myself out of bed, by say making appointments with friends early in the day helped alot. Also doing exercise really helped me. And what bilbo said is also good, and i often used lists to begin getting myself doing things again, and afterwards you can see what youve acheived in the day. I am starting my PhD in october and often worry that i will get like that again, but once you have the tehniques in place its much easier to drag yourself out again. O and also there are some absolutly amazing herbal products which really help with energy, worrys and many other problems. So nip down to holand and barats and ask. I know it seems like youll never get out of it, but if I can do it im sure you can to, considering im a stuborn mule haha. I hope this helps !!!
