Vertigo, vomiting, Year 2019 i guess?

Hello. I have been experiencing vertigo for a lot now and thi started on the year 2019 i guess? And it got worse this year and last year. We got it checked with a general doctor and they said it was just stress and gave use prescription but i dont think it really helped cause im experiencing worst of it. We haven't checked for an appointment right now because of some circumstances and im really hoping to get help here because i cant really take it anymore i think its better to just die sometimes but i dont wanna lose hope. I experience vertigo suddenly and there is no pattern of when and where it would happen and thats what scares me and resulted to me not able to do a lot of things. I vomit a lot before too but it got worse i also vomitted red particles i dont know i was too dizzy to see it clearly. I really hope someone could help me please. Im. Tired of these not knowing the reason this happens and when it would happen. Im hoping for someone to help me.
