Hello & welcome!
I'll start by asking a silly question. Have you talked to your partner about your concerns and told her that these things are difficult for you? My first approach would be address it directly. I don't know if this is the "correct" approach, it would just be my preference.
If you're able to get a diagnosis, that may further help your partner understand that these things are legitimate issues you experience (though hopefully that's not absolutely necessary). Props for your efforts thus far! I always want to correct something when I know it to be wrong, so I know how hard it can be to keep shtum.
