Would you go on a solo trip abroad?

In two weeks I'm heading to Asia for a 3-week solo trip.

I just finished my MA, and I've got a few weeks free before starting my new job, so I just thought why not? I don't really have any friends or family who can come with me or who particularly want to travel that far, so if I waited for someone else, I'd probably never go.

The thing is, whenever I tell people I'm going alone, they look at me like I've got three heads. I usually don't care what people think, but the reactions are starting to make me feel a bit anxious, like I'm doing something wrong.

I'm pretty introverted and genuinely don't mind spending time by myself, so the idea of travelling solo doesn't bother me that much. Would you do it? Would you think it was strange?
