Hi, I was wondering if anyone felt the same as me- I'm going into my third year and feel like I do have data and am collecting data, but when I have meetings and Vivas they make me feel like I don't, or that the data doesn't mean anything. I do still have a lot to do (probably trying to achieve too much), so I will probably need a fourth year to write up. I have been through a lot of ups and downs with my research and felt like quitting so many times, but I feel like I'm in too deep now. I'm still worried that I will be failed at the last hurdle.

The isolation doesn't help. I don't really have a department as such and the 'cohort' I have contains two other students that mainly work from home and don't really socialise much, so it's all pretty lonely and unmotivating. My supervisor isn't very bothered either.

Anyone get any advice about keeping motivated?

Yes, just remember that your situation is normal. Many people feel like you - google impostor syndrome.
