GTD might get you more conscious about all the pending agreements you have. If the list is just too long, your brain will not be able to project realistic success (because it believes it's impossible to do it all). That may be prone to promote some depression triggers. Hence the re-negotiation of agreements being so so important to prevent a feeling of overwhelming of a system like this.
But GTD also gets you to thing of your horizons which is good to project attractive future scenarios.
Finally, about task switch, I agree with what's been said: find your best switch rate, which I believe can pretty much be a "heart" feeling. It is quite important to realize that we are not doing tasks just for the sake of doing task. The doing itself MUST be pleasurable in the way that we feel it is aligned with our chosen path of "happiness" or whatever you call it. It's an alignment issue, not a task-champion contest...
