No worries, I understand the frustration of trying to communicate across languages, and can empathize with no much being available only in a language you don't know (so many of those Japanese-only games, for example).
There are several Brazilian members on this forum (undoubtedly more than I'm aware of, as not all users mention their homeland) and I've never seen anyone look down at them or treat them negatively because of it (which totally wouldn't be allowed here if it were to happen), so you can feel at ease here.
And in case it wasn't clear from the language barrier, if you do get into a conversation with someone who speaks your language, feel free to continue your posts in both languages in your post one after the other, formatted like so:
Konichiwa.
