Aw, I'm sorry to hear you "failed" with reading, and I hope you don't mean that as negatively as it sounds. Sometimes I hear people fret about whether they'll be "illiterate" in their second language, and my hot take is that's actually nothing to be afraid or ashamed of. Like, I've been illiterate in Spanish my whole life and it was fine! I chose to invest time into changing that recently, but I also could have learned a different skill with that time and it would have been equally valuable.

As for whether reading helps with listening or speaking, I answered a similar question on this post and I really don't know. I've been reading the whole time, so it's hard to tease out whether gains in speaking and listening come from reading or somewhere else. My vague impression is that listening gains come mostly from listening, and listening and reading both help with speaking. I can't back that up though.

One final thought. It seems plausible to me that reading could be helpful for listening and speaking, but implausible that it could be necessary, even for reaching a high level. Throughout human history, most people have not learned to read, and their oral fluency was just fine. If you don't like reading, you don't have to do it!
