No dejo de pensar un sólo dÃa en ti, estoy convencida de que estoy enamorada. PodrÃa decirte que no puedo vivir sin ti pero no es asÃ. Sà puedo vivir sin ti pero no quiero hacerlo, no quiero dejarte ir. Te extraño mucho y te amo! Besos y abrazos.
I can't stop thinking about you on a single day, I'm convinced that I'm in love. I could tell you that I can't live without you, but it isn't like that. Yes, I can live without you, but I don't want to, I don't want to leave you. I miss you a lot and I love you! Hugs and kisses.
Remarks about the translation
Extrañar seems to mean the same as "echar de menos". I'm not sure if this is a perfect translation as I'm not familiar with these feelings and it may seem a little superficial...
