Hi, new here
Just found this site today while surfing for information on all-nighters, actually!
I'm a lifelong procrastinator and I have occasionally had other addictive problems (most notably smoking, although I quit nearly 4 years ago). I too am a PhD student who is really behind and who did most of my work, throughout my life, in a last-minute panic. Even though I really hated putting myself in that position when I did my MA, I have found myself in the exact same situation now.
I have put off just about everything, from taking a shower in the morning to getting married (just now finally accomplished that, about a month ago!). I'm not really sure if I am afraid of failure or just afraid to try in the first place. I'll have to do some exploring here and see what you all suggest!
