Feeling well and bad are not opposites on one scale, but rather different brain-function. Bad feelings are often actually anxiety or fear, which lead to a broadening of attention: perceiving many different things, but none of them clearly. Exactly what is needed to get away from a situation. This is where the creativity might come from. Please note that this broadening of attention doesn't mean you can think clear, which is the problem with depression: having thousands of dysfunctional thoughts rotating, without being able to focus on one of them properly. (until the brain just shuts down with exhaustion). Feeling well, on the other hand, often incorporates feeling in-the-zone, being focussed on something, without seeing all the parts around it.
