If you want to relax, kick off all your negative thoughs, explore the nature the best and not very expensive way is to travel to the Azores (Açores).
From my own expirience I can describe my travels as the best in a couple of years. It's completely different from the traditional, travel, like city architecture, concerts, coco nuts three :)
Here you have a couple of photos of my last travel, must go there again.
