I am not having fun trying to watch shows that were in English dubbed in spanish

I would recommend watching them with the Spanish subtitles, and then later turning the show into an audio file and then listening to them passively while you do other things (e.g. driving, cleaning, walking, etc.). That way you already know what they are gonna say so you can just practice listening. Like it or not you gotta build the listening comprehension for reasonably fast Spanish.
