is03,
By leaving your family and friends behind and traveling to another country to experience new things, I think you really have to accept that at least in the beginning you are going to have to do some things alone, or you are going to be doing nothing, still alone. If you go to some of the places people mentioned to you before, you will realise that you are not the first one, nor the only one that night, to enter the place alone, and that people are there to meet other people. Nothing really terrible should happen to you if you enter say, a bar in the Shida area like Roxy Jr, alone, and then just sit at the bar. The worst that would happen is you stay there for an evening and nobody talk to you and you talk to nobody. But, that is highly unlikely. At the very least, you will know what it’s like to go somewhere alone, and you should feel more confident about doing it again.
If you can’t go out late at night right now, then why not just go join something like the Hiking club, even if you don’t like hiking. You have to meet people to meet more people, and again, this is some kind of social activity, if the members didn’t want to meet new people, they wouldn’t go posting their meet-ups on this forum.
Actually, Tommy’s advice about going to the same place regularly is good, and this is how I met a lot of good local friends.
I was also wondering, is that group ALE (Actual Living English) still around? At least for me, it was a great place to meet new people and see parts of Taiwan when I first arrived here.
