What do y’all think

So I’ve had fever seizures as a baby up to is say 2 yr old and the rest of my childhood I had none but once I turned 15 I started getting at least 3/4 seizures a year every year to this day. I’ve had two so far this year. My ct scans are normal also mri normal but I just did my eeg scan today and I have to wait for my results. Could it be a tumor or something serious I’m so scared. Would it have showed on the other scans? Dr said maybe it’s lack of sleep or something idk I have so much anxiety I’m scared thinking it’s something very serious. If it was serious would it show on the other scans too. Or just the eeg. The dr said I do have epilepsy I am having seizures they just don’t know why that’s why they did the eeg today. I have a bit of memory loss my vision gets a little blurry sometimes and I have seizures sometimes and that’s really it. 😭😭😭 I also get headaches sometimes. I’m 21 now btw!
