Hi! In addition to the advice they will give you, my opinion is that meditation in itself is excellent for managing stress. Consider that meditating is time you spend alone with yourself, without focusing on problems, but only on your meditation.
When you meditate it's as if you take a moment all to yourself, a sort of "escape" from the constant stress of an excessively overstimulated society. Since you can take half an hour to meditate, in my opinion something like this is worth much more than very long journeys to reach relaxation destinations such as distant beaches or exotic places. You can actually find within yourself what you seek outside of yourself.
Obviously traveling is a beautiful thing and taking time for yourself is equally beautiful, what I'm saying is not to underestimate that meditation itself is something that cannot be touched by problems and stressful crises.
Do void meditation regularly to have the ability to concentrate on your meditation and you will see that it will be worth it as if it were a break from stress/moment of total relaxation. I don't know if it will solve the headache, but you will definitely be able to feel more of yourself introspectively.
When you are overstimulated, you can consider some relaxation techniques, such as breathing exercises, trance, or similar, to then put yourself in the mental state to meditate. I always do this.
It is for these reasons that I recommend, when it happens, to see meditation as an opportunity to feel good and not to experience it in an anxious way (as some do). Meditation is exactly the opposite of any anxiety or negative sensation: it is precisely a moment in which we can feel good about ourselves, between ourselves, for ourselves.
In addition, on all this, this article will help you a lot with these things:
I would also like to say that Hatha Yoga is DEFINITELY effective in these situations. I think it is really something very useful in this sense. Exactly as the article I linked to you suggests. Hatha Yoga really helps a lot. HPS Lydia has written many Yoga articles, including many explanations of positions for Yoga sessions.
