I saw your recent update that you have decided to stick with the PhD. Would you mind elaborating a little on how you arrived at that decision? I'm also in my 3rd year and really struggling, with very little written yet. I have very low motivation, but I think a lot of that stems from feeling intellectually way out of my depth (not being able to understand the material or write at the required standard). People don't seem to believe me though and I keep getting told that doing a PhD is just about slogging it out and there seems to be an assumption that because I started it, I must be clever enough to finish it. I appreciate this aspect might not apply to you so much, but I'm sure hearing some of your thought process would be helpful, if you want to share. Thanks.
