As far as the headaches go when you feel like crying but can't/don't. My therapist and I have discussed this quite a bit. Fir me it happens when I either suppress emotions or have a freeze response. For me in both cases it is because in both cases I am holding back emotions that need to come out but am avoiding intentionally or intentionallly. She believes the headaches are a sign of progress for me. It means that it shows I am starting to feel things in my body even of it is the pain. For years I never noticed pains or discomfort in my body unless it was extreme.
