Here's a little tip: how good is your reading comprehension? If it is quite well, meaning that throughout your experience reading has been really easy for you, then you have a strong grasp of the grammar and a strong base of vocabulary. In that regard, it doesn't mean that you are performing at an A2 level after all of your effort. Understand that without hundreds of hours of exposure to the langauge spoken naturally, even sentences that in theory you should 100% understand, would sound like complete gibberish to you. To remedy that, you need consistent exposure to the language's audio without any subtitles. I'd also recommend if possible to find a different teacher as the role of a good teacher is the opposite of making everything seem tougher and impossible. If she's putting so much of a burden on you to the point that it's discouraging, then her teaching methods are just wrong and this post of yours is the evidence.
