Frequent Headaches and Vertigo: Seeking Advice

Hello, I have a question related to symptoms that have been progressing over the past few months. (If I were to guess I’d say it started a year ago but started to progress 5 months ago?) I used to be someone who would never get headaches, almost never get carsick and NEVER get vertigo. These past few months I’ve started having headaches multiple times a week, I’ve experienced vertigo far more often and even being the one driving gets me dizzy & carsick. I know I need to speak with my doctor about it, but I’m currently paying off my last expensive doctors bill so I need to wait till I can afford another one. These symptoms are pretty vague too but, have you every had symptoms like this or know what it could be?
