I have been few months into a fully funded PhD (Engineering). Over the past few months I started loosing motivation , interest, and concentration and as a result started affecting my confidence . I know this is so far the best opportunity I have got, but I don't think I can carry on like this.I am in a dilemma , I would n't hesitate to quit my PhD but I have no answer for the Q "what next ?" ....I don't know what to do really.
