I had a feeling I was coming through this patch of anxiety. My head is hurting, I've got a feeling of pressure on top of the head and got brain freeze too, it's driving me mad. I know it's nothing bad but it's really knocked me for six. I feel like crying and I told my Mum who said stop being so worry and live a little. I hope this feeling passes soon or I will go back to the doctor for this and I can't keep doing it!
