Well, a lot of people automatically lay down or stay in bed when they already feel depressed or anxious. It's a good position, as "laying down doing nothing" is pretty much as close to minimizing one's own metabolic rate, nervous system usage, etc. as possible. However I'd say that "laying down because it's all I can do" and "laying down as a conscious way of attending to my personal exhaustion" are two different states of being, with an important difference. The first could easily raise one's anxiety if it seems counter to "what needs to be done" while the second approach is part of a more analytical process (at least in my case) which is hopefully accompanied by fail-overs and follow-ons, like addressing stressors, mentioned above.
