What’s wrong with me?!!

About four weeks ago I started getting dizzy just randomly and when I turned my head, and the last about two weeks( I think just know it’s been happening about half the time of the dizziness) every single day I wake up and have a headache it’s just always there . And the most recent thing is I think what I want to say bit it just doesn’t come out . I know exactly what I want to say but my words just jumble. Any idea what this could be? * I am going to the doctor as soon as I can but I’m worried and want to know what you guys think

*edit to answer, overall healthy not obese . Only health issues is pcos . My family has history of high blood pressure. No stress increases of diet change.
