What foods do you eat? What is your lifestyle like? Are you spiritual or religious at all?
Most importantly, I think you should google ascension symptoms.
I doubt it is diet related.
Magnesium won't hurt to take, it'll help calm you, and the adrenal glands. If you are constantly in a state of adrenaline, you may be feeling this way too. Eventually that can lead to adrenal fatigue, and you will become very exhausted, but in the beginning stages, you are usually full of energy, and agitated.
Stress, anxiety, and agitation are mostly caused by environmental, mental, emotional, and psychological factors and the cure for that is eliminating the causes of stress, overcoming fears, working on psychological issues, releasing any past traumas, doing a lot of self work and most importantly finding relaxation techniques and adding things like meditation into your lifestyle.
If your lifestyle is too hectic and busy, you need to find ways to relax.
Use discernment. You will have people telling you that extreme diet changes might be necessary, however I encourage you to properly research effects of euphoria. It is actually dangerous and unhealthy if sudden, extreme diet changes are making you feel euphoric, it's the first stage of delusion in starvation, like in anorexic patients who feel literally amazing as they continue to starve themselves to death, but when this mental condition is caused by lack of food or nutrients, like in extreme low carb diets, it eventually leads to water loss, brain damage, mental problems, irritable mood, and overall bad health. So especially when you have been feeling not entirely mentally stable, euphoria may seem like a blessing in disguise, but please be aware of it. It is not actually healthy.
To gain a real healthy, calm and balanced and energized sense daily, you'll need to change lifestyle things. Food is just one component of body, mind and spirit. All three must be functioning well.
There are a bunch of relaxing things you can add to your lifestyle. You need truly relaxing things, but also add things that you have a passion for.
Physical activity will help with all the above. People who suffer from fatigue will benefit from it, as physical activity gives people more energy, not less.
People with overactive adrenal glands might become prone to addiction to the endorphins and adrenalin in physical activity, but that is a good thing. Working out will make you happy. It's a natural anti-depressent and mood stabilizer. Just don't overdo it.
For better mind clarity, mood boosters and relaxing benefits, try getting into cold swims.
Lack of sleep will make it hard for you to think properly and focus. Try natural techniques for sleep. When I used to have problems I drank that sleepy time tea or took melatonin, but mostly what worked for me was meditation relaxation techniques.
The one I used to fall asleep was imagining white light upon every breath going through every inch of my body, starting with each finger, and ending at each toe.
Also make sure to establish a proper sleep routine.
Hey thunderseeds, thanks for the response. Even though this is a raw paleo forum, I do not consume any raw meat (tried it and could not handle it, even 100% grass fed and finished beef). I eat raw coconut oil, pasteurized butter (president brand, raw butter is expensive), olive oil (COOC certified), grass fed beef and lamb, fruits and leafy greens.
I do have fears and emotional factors... directly tied to acne and my appearance (and being accepted by others).
