I, for one, was born with only the knowledge of spanish but my friends in school were not, just like it was hard for me to learn english but i persevered anyway because i knew it was better for me, i imagine it is difficult for you. People do learn at completely different paces but if you study for just 20 to 30 minutes a day and you’ll be able to learn the language in no time. Also do not stress yourself, if you don’t understand something study it for five more minutes and leave it alone because maybe you’re having a bad day and you’ll learn it tomorrow. Just be patient and don’t give up because it gets difficult at times.
