Brain tumor scare?

[Eggplant3458]

Hello! I am a 16 year old girl with the typical hypochondriac fear. About 3 years ago i had a throat tumor scare because i would have trouble swallowing. Well not trouble i wold just feel there was a lot of mucus. Now I have a brain tumor scare. The worst thing I could have done was googling my symptoms. My symptoms include sometimes not usually i get morning migraines with nausea. They start at about 7 am and get better by 9 am. Also I get these little short mild pains over my head that last 1-3 seconds. I don't get as many as I used to. Also I rarely feel these short burs of a tingle feeling in the back of my head. I have constant arm and leg jerks. But when I googled the symptoms one of them listed seeing double vision now i swear I see double. Like if i am watching tv and i am on my phone and i look up to view the tv but i'm still looking at my phone i see double but it goes away when i look at the tv without looking at my phone and i have never noticed this until now that i read that double vision is a symptom. Not sure what to do. My mom thinks its just health anxiety and that a ct scan isn't necessary because she doesn't want me exposed to that radiation. Could it be an anxiety disorder? I couldn't use some reassurance please if anyone else is going through something like this! I also do get anxious a lot. Like I worry about a lot of things. I always think the worst case scenario.
