I'm happy to find people going through exactly the same thing as I am, although it doesn't make it any more fun... I too lack motivation to walk those final 100 meters of the marathon and rather sit down and give up. Utterly bored with the exercise. I was afraid that this would be a bad sign for my future in research....Now that I think of it: I'm actually still afraid it is :-( ...sulk...

Hi,

I can totally relate to your problem. I'm almost at the end of this long, dark tunnel (I need to finish by mid-August) and still feel insecure, incompetent and a fraud. Still sh*t my pants if I have to present my work at conferences, that never went away. I tend to do the same time-wasting activities as you are whenever I get stuck in stead of asking for advice (I am doing just that, as I am typing this). Somehow I managed to stick around but don't ask how or why... I have no idea. In a way I know I have reason to be proud of what I've achieved in the end, but I still feel incompetent, as if it's not my world that I am operating in. I'm glad I persisted (for the sake of persisting), but I'm not sure if, given the chance, I would do it all again...

That said, I think that everyone who has an interest and the opportunity to do a PhD should do at least one serious attempt. Give it your all!! You are still in the early stages, and it sounds like your supervisor is ambitious with you (good thing). Great that you already see you have a problem (which can potentially become a huge one), now you can work on it. It's definately not too late, but also certainly not too early to drop a (small) bomb and wake up your supervisor and yourself. Don't indulge in your passiveness and fears (I did, and that is the thing I most regret). Don't end up in a situation in which the only one you can blame is yourself. Talk to someone, to begin with your supervisor! 

Tip for the writing: write down what you want to say, just for yourself. The "delete" and "backspace" buttons on your keyboard are prohibited. Don't have the intention to show this rubbish to anyone, as you are going to write it down in baby language. Just to get to the bare essentials of what you are trying to communicate. This is quite a difficult exercise (make no mistake), but it helps to organize your thoughts. You can then build on that and translate it into science. That's the easy part.

Good luck!
