Dear Jen
you are doing a great job with the journaling. i am glad your T gave you good feedback about that, and i hope you feel more comfortable with it.
i just want to point out that just because the headache is not bad enough to keep you flat on your back does not mean it's not a migraine. migraines can vary significantly in severity. there are also acephalgic migraines (no headache - only other symptoms). the fact you started feeling sick also suggests migraine to me. again, nausea does not mean you feel like you're gonna throw up. it can be milder.
i hope these spells.... you have enough troubles. unfortunately stress can exacerbate them, and when we don't/can't sleep we are more stressed.
keep hanging in there. not long to go now before your appointment with the sleep doc
