You may want to replace that perception with a more positive one. From "I hated this language at school" to "this language is fascinating" or "I love the culture and want to learn more". It can be any perception that appeals to you. Perceptions affect everything we experience. If your perception is I hate this language, every difficulty you face will remind you of why you hate this language. If you perception is "it's different, it's interesting", faced with the same difficulty, you will be curious to know more.

As a kid I couldn't learn German. My grand-father was a prisoner in a concentration camp. I grew up watching movies about the war. I had a terrible opinion of Germans and Germany. As a result despite taking 4 years of German in school, I never really learned it. I realized later in life that I had missed something, that the German people I was meeting were really nice and that I had let my prejudices prevent me from learning their language. On the other hand I had learned Greek very quickly. At the university I had been welcomed in the Greek student community and got to love everything about them. So I learned German from Greek, using textbooks written for Greek learners of the German language. Now I don't use as complicated a path to learn languages, I pay attention to my perception and make sure I have one that is motivating to me. 

Have a beautiful journey in your language learning.
