I am doing a PhD in engineering and for the first 21/2 years, I did very well. However, the past 1-1/2 years have been bad. I have been learning a lot but I am not making any progress. Now, I am feeling angry at myself for not having focus and direction. I don't know if I should quit or keep going. I need to find some new found motivation, but I do not know where to get it. Have you any suggestions for me. I am really depressed right now.
