Procrastinate until you feel so bad about it that you fall into a depression. The only way to get out of the depression is to get started. It can take up to a few months/years, but it will get you started at some point. Works for me every time.
of course, as a side effect, you'll start to only work, being wonderfully productive as the depression wraps everyone around you in your irritability blanket and snuffs the life out of your relationships
...but hey, it keeps you productive
it does work, but as you note, it's not sustainable. It's horrible for the mind and body.
please take care of yourself -- overwhelm is the pits.
If what's stressing you out is the work you have to do or where you're working, now is actually not a bad time to search for a different workplace. You don't have to prove anything to anyone if that means that your mental health takes a toll, and you'll not be able to prove anything anyways in such a state.
If it's something different then feel free to chat here, or write me via mail(if you want to vent to a stranger), or look after your mental health by visiting a professional, if that's possible for you.
Are you able to take any time off to decompress at all, or have a mental health professional you can talk to about it?
I'm fighting the urge to tell you all sorts of different things that I've tried and have helped me in that spot -- but I recognize that's probably not what you need.
do you have any sense of how a random group of HNers could support you? If nothing else, I hope knowing that you're not alone in the experience helps.
