Hi there Glenncoco88 and thanks for your post!
Yes it is very true as per the other responses, that stress and dehydration cause headaches.
I'd like to add one more thing if I may, to do with relaxing your way out of the headache. I suggested this in another post I wrote and would like to repeat some of it here as it is very relevant.
I wonder what it is that
might be causing your unease or uncertainty?
If you are able to perhaps come close to
identifying what it is and share it with us, we may be able to help a little
bit. It matters not how trivial any issue may seem, if it bothers you it is
able to be discussed.
When I was hit by anxiety over
the years I found a song that really helped me. Its the old Doris Day song
called 'Ke Sera Sera, what ever will be, will be, the future's not ours
to see etc'. By using the words for the chorus and singing them to
myself over and over like a kind of mantra, it seemed to work like meditation.
I always feel calmer after this song as it sticks
in my brain and I hum it for ages.
Yep the song might be just a touch corny, but respect it and try to make it your friend.
We can't really control the future, but can prepare
better for whatever might happen by relaxing into it and taking an 'If it
happens, it happens' type of approach.
After all, what's the worst that can happen? life
goes on and there is every chance you will look back on this in time to come and
see it at a learning experience, a speed bump that set you on a better course
to self belief.
I am very happy to discuss at any time Glenncoco88, just get back to us if you want to.
Hope this has helped a little bit.
All the very best, The Bro
