I'm scared this is s sign of a brain tumor?

Also forgot to say I feel disconnected, sometimes I have a hard time remembering, I feel sometimes my arm isn't my arm, feel like I'm in a dream, sensitive to light, arm/hand gets numb, feels I lost feel and conscience in part of body, very tired, I had episode of feeling I was being pulled back, on a boat, dizzy, sick feeling, off balance, legs felt numb and weak I believe my ears felt clogged afterwards, when I was little I would zone out I would be talking or doing something when I go into a trance and I'm not there I'm completely gone like I was never on this earth my mom said I would start to slow down and slur my words then stop and freeze for a minute, I grew out of it but at times I get it also before my period at times

So scared I have a brain tumor since last December I feel faint, dizzy, off balance, weak, feel I'm on a boat, sometimes feel stuff is moving around almost if the room wants to spine, the room changes color gets dark, my vision gets blurry, I see sparkle little lights at times, sometimes recently stars, blur light. I really don't have headaches but my ears get weird at times ringing or like I have a dog whistle in my ear feels like it's going into my brain. I'm always on my iphone, I'm very stress, I have anxiety at times I'm 18 years old female

If one more person on this website asks if they have brain cancer
