I Have A Vestibular Disorder With Mild Nonspecific White Matter

I have a vestibular disorder with mild nonspecific white matter disease related to chronic microvascular ischemia. neurologist has given me sumatriptan succinate which does nothing for the migrain headaches, at times I feel like just ending it all the migrains get that bad, am I about to have the final stroke that will leave me with paralysis or end my life?
