Well if this isn't interesting to hear... I'm on my first PhD year and I've also had a mental breakdown! Not the mention the every day tiredness and stress.

I can't even tell what is so stressful about the job. Maybe it's the lack of guidance!! I just sit in a room and no one tells me what to do! How frustrating is that? I go about doing some research and programming my stuff, all the while I drift further away from the other PhD students (who for some reason seem to think it too tiresome to speak to me). My friends that are still master students all finish right about now so soon I will be - alone.

Yes, I'm a melodramatic person.
