I can understand your difficulty with English. I too struggled with English as kid because I'm dyslexic. I'm dyslexic so I lack natural ability to distinguish phonetics sounds in English. Fortunately, my parents sent me to private school where it focused on phonetic sounds. So I suggest you look for videos on YouTube to hear sounds over and over.
As I am learning Spanish now. My greatest difficulty is grammar structure. I know I will have difficulty mastering it but I'm very determined. I study about 2 to 3 hours a day with Spanish application. I have a weekly tutoring lessons. Most of all, I watch movies and TV shows in Spanish. I listen to radio in Spanish and I try to find Spanish speakers.
All and all, my learning habits are nontraditional as I have learned phrases and words as I learn grammar backwards.
