im 21 years old & i have been suffering really bad migranes.

it affects my daily life an it make not want to move outta bed. today i have a bad one & its making me cry ive been to two different drs and all they done was give me pills neve got a catscan done for my brain. i don't have the money to go back to the drs cause all they do is give me pills. its hurts to keep my eyes open. i seriously don't know what else to do for myself. yesterday i was outside cutting grass in the heat i started to shake really bad and felt like i was gonna pass out. i came inside to cool down n i about hit the floor i caught myself i was shaking so bad then i got this headache and its kept me up all night.. please help if you all have any home remedies or what i should do? my moma nd all is like it just from not use to being outside push mowing but i seriously think theres something else going on.
