Dizzy/ Anxiety

I’m 17. Once and a while I’ll get this weird feeling in my head. Today I felt fine and was making lunch and I got this feeling it my head that made me feel like I was moving/ vibrating. It didn’t last long but it scared me. I also have bad health anxiety so ik my doc will blame it on that. Ever since my anxiety has gotten bad I’ve felt weird things. I’m just scared it’s a brain tumour or something. Thoughts?
