Seizure or stress and anxiety?

Hello,I'm a 14 and a half year old male currently stressing over about how I've been feeling over the past couple days and wondering if it's epilepsy and a seizure or just really bad anxiety and stress. So about 4 days ago my arms and legs felt a little weird so me being me started questioning myself saying what if this is something serious what could this mean.Anyway as the day progressed I worry and overthink it when really my arms and legs might only feel like that because I've done alot of bike riding. The more and more I think of it I start to feel weird and start to have these weird feelings like derealization, fear and anxiety which all sound like a normal anxiety attack which I thought would go away by the next day after sleeping. The next morning I feel alright but when I get up and start moving around I start to get derealization again and then I get scared about it and then my anxiety comes back and basically I feel the same as the day before. During the day those feelings will come and go and when those feelings do come back it's a feeling of fear and I worry what if I have a seizure. With all these thoughts running through my mind I end up typing up my symptoms and when I do I get results saying that it's an aura or a seizure or just anxiety. But me being me I will go for the worst one and worry that I might be experiencing symptoms of a seizure and that any time now I'll have a really bad seizure which scares me alot. That night I end up going to sleep and hope that in the morning I'll feel normal again. The next morning I feel the same how I feel alright but then when I get up I get derealization and then anxiety and so on but it doesn't last the whole day it's on and off. This time I start feeling more things like muscle twitching like my head would jerk a little or my neck, leg, foot or my arm just a little though. Which got me really worried so now I'm worrying even more. The next morning I woke up and my arms and legs were a little shakey I don't know why tho but it seemed to go away but after that I started to feel normal again and I started think I was getting better. That day I was going on a bike ride with my friend. When I start riding my bike I started to get derealization again and when I got to the train station which is just up the road from my place I was worrying that might have a seizure and if something happens what am i gonna do and yea basically stuff like that I was getting really worried. Then I had déjà vu and I start feeling a way that I can't really describe and I remember reading on Google that that's a symptom of a seizure which scared me to death. Through out the day those feelings started to fade away but they still come and go. So right now I'm stressing out that all this is because of what I stressed and worried about in the first place or if it's symptoms of a seizure that is coming. If anyone has any idea what I have been going through I would appreciate it very much. By the way I forgot to mention, I have never had a seizure in my life neither do I have a family history of epilepsy or seizures. Also I had a migraine last week with visual symptoms I don't know if that relates to this but I'm just gonna mention it anyway Thank you for your time
