Sometimes, one just has to “restart” their language trajectory. Some 30 ago I took Russian at a well renowned, competitive university. We had a fabulous time in that class, especially at the weekly “conversational seminars” where the professor bought pitchers of alcohol for us underage students. Unfortunately, at the end of the year it became clear that none of us had learned more than a few words of conversational Russian, despite us all having reasonable grades in the literacy section of the class. Admins at this University, aware that some students were not up to par, instituted a new rule in which we were all forced to take an oral proficiency exam in order to be admitted into our 2nd year class. As you may expect, my entire class failed that exam (perhaps we would have done better with vodka in hand, given the contextual effects of learning.) Having failed, we were given the choice of retaking Russian 1 and 2 (for no credit), or switching to an another language (our program required oral proficiency in a language to graduate). The entire class switched to other languages (I did Hebrew, another did French, another did Spanish, etc.)
We all survived, and turned into highly successful, happy people. We still happily reminisce about our Russian class.
The upshot is: do as other posters suggest – start a new language. Sometimes there is no going back. You will be fine!
