It could be Lyme, as vcast said. I hope someone on here can direct you to a Lyme literate doctor, which you need to for a proper diagnoses and to get started on treatments soon. Someone will email you if they know of someone, since we're not allowed to post doctor's names on here.
I live in a part of the US where it's not widely known. We have rainy winters like you do and that can make symptoms worse when we don't see the sun for weeks.
Keep us posted and stick around here to learn more.
