Hey all.
I am doing a PhD in engineering and am 6 months into it. I am an undergraduate hall warden and so get a free flat with free food etc. and I get paid to do the PhD. I turned down a decent graduate engineering job for this as overall it worked out that I had more money doing the PhD than if I was in industry.
The problems are that since I started in October 2011 I have found the PhD very difficult and I find the academic papers are nigh on impossible to understand. I find the whole process very lonely as I am in an office with older researchers who have families and are either at the end of their PhD or have finished their PhD, plus my friends from my course (undergraduate finished last year) have left and a few other friends turned out not to be the friends I thought they were.
I feel like I extremely unhappy and am unsure what to do. I want to leave the PhD but I know that this is a once-in-a-lifetime opportunity that I am throwing away.
I realise this is in GD but I hope at least a few answers will be sensible
