Resources more for reading/writing than speaking

Hello!

I've been super happy with my progress so far in the alphabet and want to start learning more grammar and vocab. I have Anki for vocab, but I've been struggling with grammar resources. I've found many YouTube recommendations, but they're not what I'm looking for. I have audio processing issues and videos are difficult for me to follow, even in English. I've been learning tones by repeating the same sound files over and over, but even then I struggle to hear the difference. I want to be able to read more than converse at this stage, even if it's not the usual way to learn.

I hope there's some place that will help me with this. Thanks for all the help everyone has given me so far, I really appreciate it! Thank-you!
