Thanks for your confirmation that I am not alone and the ONLY way to finish it is to JUST DO IT!!  And thank you for this forum in giving me the chance to scream out and be understood! But now I will try to focus on the positives, which are many if you actually write down what a PhD means to you.  I was ambitious and enthusiastic once, so i can be again. So I will be deregistering as pessimistic "Falling" and join in as a more optimistic participant.  Change your negative thoughts to positive ones - use the antonym instead. I feel valuable, intelligent and proud! 

Hello all. I'm a new member to this forum (actually my first ever forum!) and I am here searching for the light! It has been 3.5 years, i am writing but VERY VERY slowly. I have very little motivation left and I just can't seem to discipline myself to finish it. The self-critisim is the hardest thing to deal with as i had always been very optimisitic and confident. Now i feel useless, dumb and embarrassed!!!!
