I have developed severe muscle twitching apparently due to anxiety. They get worse when I try to relax or when I try to sleep, and they stop when I have a panic attack.

I'm super scared that I will develop a seizure due to it. I hate not having control of my body. I'm fucking terrified

I've actually gone through an EEG testing to be tested for epilepsy late in 2016 (I've never had a seizure but I've always suffered from a lot of hypnagogic hallucinations and sleep paralysis so they wanted to rule out epilepsy) and it came out clear. 

I literally can't relax because everytime I try to relax I twitch so much that I think I'm gonna get a seizure.

I also popped a 25mg hydroxyzine which I've been prescribed to take at night time against my anxiety. You can't take those if you are predisposed to seizures. I feel calm I guess but I'm still twitching and I'm terrified they're gonna induce me a seizure. I've taken these once before though.

Can someone reassure me that it's physically impossible for me to just get a seizure rn?
