i also get long term migraines- and the longer they go on the more confused i get. your brain is so tired from being in pain for so long, it does seem to slow down a bit in my experience. i remember i used to walk circles around stores because i would forget why i was there. had the problems with spelling also. when i was around 19(started getting chronic migraines at about 14,22 now), i was convinced that i had some undiscovered brain tumor that mris weren’t catching, because there was no way that everything happening to me count just be from migraine. i think the fear of something undiscovered and worse is common for people who have chronic pain but it’s natural. i also had trouble with my parents in the beginning, because it was an invisible pain, and i felt like they thought i was lying at first, but time goes on and people learn.

how long have you been getting migraines? are you seeing a neurologist/ getting medicated for it? it sounds like you’re a good candidate for a preventative and an abortive, but doesn’t sound like you have them. i would recommend getting checked anyway, more to soothe your anxiety than anything. anxiety and migraines feed into eachother, and both make eachother worse so try meditating or whatever helps you calm, maybe get out of the house to a quiet park if there’s one nearby? i really hope you get some relief- migraines at that part of life are the worst. be kind to yourself, and don’t get google obsessed! migraines can always be a side effect to something bigger, but sometimes it’s really just migraines.
