I love south america too much...?

I went to south america for three months and tried to learn spanish there. i didn't have a great time because i was by myself and things didnt always go so well (loosing credit cards, getting lost, spending too much time going out which i dont really like that much) but i fell in love with buenos aires and argentina (well probably every part of south america i visited really) anyway. i just can't explain what it is about south america but its been a year now and i still cry and wish i could go back all the time. i dont dislike my life here, im actually really happy most of the time now but whenever i think of south america i feel empty and sad. its like theres a magnet inside me that just keeps pulling me back. its one of the strongest things iv ever felt, and i just dont know what to do. im studying here and its just not possible to go back at the moment. i dont know how to forget about it, or even if i want to. has anyone else ever felt like this about a place? what did you do?
