Im going insane

I’m having really bad fear and panic right now. About a year ago I started getting twitches all over my body. Now I sometimes had this feeling in my LEFT HAND that it was somehow weaker. Yesterday I also felt like my foot was weak, but not extremely bad, and there was nothing noticeable.

Yesterday my right hand suddenly became more shaky, like when lifting a glass. Twitches in my right shoulder started . After that I went to sleep. I had been lying on my right arm, and when I woke up I lifted the arm half-asleep to lift my blanket because it was hot, and my arm immediately dropped down. Kinda like I couldn't lift it, as if my brain wants to but my body doesn't allow. After that I tried to lift it again and it didn't work, but the third time I could lift it again normally. Also I've been having calf cramps and a stiff calf despite taking magnesium glycinate and a b complex.

Thanks for reading. Maybe someone can tell me if this is concerning. Oh and btw Tbh I was always scared of these Twitches but I just shook it off. But this incident made me worry badly.
