I'm scared I may have a brain tumor?

(ps I'm a 15yr old girl) recently my health anxiety has gotten out of control. I've had headaches in the same spot, a dull pain right along my brains motor strip. I think that means my tumor is inoperable. twitching and random numbness have accompanied these strange headaches. I went to the doctor twice about scares of ovarian cancer an they toolk blood, that would show cancer right? I'm terrified of feels so much realer than any of my other health panics, it's been 5 weeks on the same symptoms. my parents won't take me to the dr again, probably because I'm the little boy who cried wolf, so I guess I just let it metataphasize into more.....
