There is a lot of meaning in your experience, although you many not notice it now.

First of all, you are not alone. There are a lot of people surrounding you… but they aren’t your friends. Slow down. Friendship needs vicinity, sharing experiences and expectations.

Second, maybe you should take this travel as an inner journey. Trust yourself, trust life, trust your future friends. Do not wander too much about your past.

Third. What problem do you have with feeling alone? Meditate about that. The worse thing that can happen is that you will get bored or will be unable to share your experiences. Is that a problem? Do you really think you will not get along with someone in the near future? Friends come and go. In the meantime, you remember yourself, you talk with your inner side.

I recommend you to read a book: The Outsider by Colin Wilson. The kind of feelings you are experimenting is well documented there. So you will understand you are not alone.
