Stress

[peater]

, Sometimes I just wake up and feel stressed out for no reason, combined with a feeling of emptyness, like nothing matters in life, no motivation, then the rest of the day is ruined. Is there any reason for this? And I can also sometimes just be happy then suddenly be stressed out for no reason, high serotonin?

Could be something as simple as mouthbreathing in your sleep or low quality sleep in general, then you'd wake up with stress hormones elevated more than normal. I'd say try blue vervain, Do you wake up dehydrated?
