So sorry you are going through this. I used to get migraines too (though never as bad as yours!) and it is not fun. Have you ever considered food intolerances or chemical sensitivities? The latest research really supports those possibilities. Most doctors will automatically say that food allergies or intolerances (the two are very different) are not the problem but it is interesting to me that they are NOT able to tell you what the problem IS! This is so common and it is why so many people are now doing their own research to relieve their symptoms. I am not a doctor but I consulted a nutritionist who told me to go ff gluten and dairy and the difference in my health was amazing! You may want to consult one!!!
MSG is a common cause of migraines and is in so many foods and especially in gum. You may want to try staying away from it. Some people are sensitive to cleaning products and get really bad migraines and even seizures from them.
Food intolerances can cause inflammation of the intestines which causes problems with absorbing nutirients. This causes an array of symptoms including migraines. Low magnesium is often a cause so that might be a good thing to get checked:

Celiac disease or the less severe "gluten intolerance" is a very common cause of migraines. Gluten is found in wheat, rye, barley and can be in oats. (Other foods such as dairy can cause migraines too.) Just go on line and search "gluten celiac migraine" and the information will be endless. Do all the reading you can! You can also search "gluten intolerance symptoms to see if you are having any of the other problems related to this condition. The list is huge! It is very common and many doctors just don't get it yet. Symptoms can include but are not limited to anemia (low iron or low B12), dizziness, fatigue, bone and joint pain/aches, stomach aches, nausea, mental fuzziness/difficulty concentrating, skin rashes or itching, shortness of breath, blood pressure issues, blood sugar problems, fainting, mood swings, chronic yeast infections, thyroid problems, weak fingernails... It goes on and on! Celiac disease and gluten intolernace have been linked to many cancers like lymphoma and to autoimmune diseases such as lupus, MS, and diabetes. The condition tends to run in families.
