In 2 years I will be free to do what I want with my life, be it work, go to university or even be lazy. Recently I've felt the need to leave my home and see as much of the world as I can. I've always wanted to travel, but I can't speak any other language, so that kind of restricts me there. California has always fascinated me with its style and culture, and I would love to see it one day. I live in England and have no family or friends in America; so I would completely alone if was to go. I could always find new people and make new friends, but for a while at least I would be on my own. My entire life I've had family or friends around me, so I'm cautious of leaving all that behind. Are there any Dollars here who have done something like this? Left their life at home to explore and see a whole new culture in a new country? If there are, do you have any advice? Was it a good decision? Is it an easy transition? Was it all worth it and would you do it again? Any kind of help is appreciated. Thanks for reading!

whether it's a good decision or not is up to the way you handle it. You'll need to have lots of money to live in California depending on the city though. I love in Texas and the one story house I live in that was around $200,000 would be half a million in San Jose, and a good 650,000 in Los Angeles. Same with New York City, so living in a home or apartment in those places right when you graduate is out of the question. Even shitty apartments are pretty expensive. If you're planning on using California as a place to stay for just a little while to explore and adventure try finding a friend online (be sure it's 100% safe). As for not being able to go places because of a language, have you ever considered backpacking or something similar?? You can grab a friend or something and travel lots with a smaller budget, and just learning small bits and pieces of the language would be enough (greetings, conversational stuff, restraunt vocab). All of that will contribute to a better trip. Just have fun with it, being too worried will take away the fun aspect.

>>1 I understand the need to travel and see new things, I also know people that took a year off after they graduated high school to just travel around. What I think you should so is work a bit (like part time or just enough that it doesn't disturb your studies,) until you graduate and save up money for this trip. Travelling with a friend or a family member is probably a better idea so see if someone would like to go with you.
You have two years, do the research and do the proper planning. Find out which places are tourist safe, what hotels and travel lodges are nice, tourist destinations, where good restaurants are, the amount of money you'll need, how long you can stay, things like that.
Be wary of the online friend thing. I personally don't think it to be the best idea but just be 100% sure that they are safe to visit.
Consider other places that you can travel to instead, I hear that it's fun and easy to backpack around other parts in Europe, you may want to further extend your research.
Just don't cheap out where it's needed, make sure to stay safe, be careful, and have fun! I hope that this helps :3
