I grew up with Spanish but somehow got English mostly ingrained in my brain between English classes during prescolar I didn't remember until years ago when I was told about them...and roaming the internet for a long time while sometimes getting into forums and later on Discord servers.
It feels interesting because of how a lot of times I just write straight into English despite Spanish being my native language, probably because I've got used to talking about stuff that tends to have a bigger audience in English speaking sites or chatrooms.
I definitely don't know a lick of German, Swedish or any of those other languages you mentioned though. Really interesting to hear that because of your childhood and growing up through school in another country you have learned that many languages.
Oh, and by the time you are reading this...Merry Christmas!!
