I am loosing my memory, please help me

I'm 20 it makes no sense for no one but I am, it started with big things and now with huge things,I know that Border people struggle with memory, my teraphyst made me a basic test and said it's totally ok. I just trying not to freak out so I am asking here and not in others subreddit because maybe it's common. I forgot something stupid things ( what I ask to her 1 hour ago?) And I repate always the same stories bc I forgot I still said. But I forgot even huge things, the years when my sister is born (then I remembered on my own) and even how to spell words, that happen in Italian ( my native language) and in English, maybe is because I am became bilingual but my sister is almost bilingual and my best friend is totally bilingual and I don't see these problems except "I don't remember that word in Italian) but often I don't remember words neither in English neither in Italian. And I know I am not doing so much spelling mistake but is due to switchkey. One time I was thinking if that's grammatically correct to put an H in a VERY basic words ( ice, "ghiaccio" in italian) and this really scare me. I don't know if is normal for a border with a few memory who's even almost bilingual to have such problems with words (I read a lot often in Italy, there's no so much choice for English book here). So, someone who's not a native English or American or someone who's basically a bilingual in another lenguage can say to me if it's normal?
