How to overcome worries/fear in a foreign social setting?

So I want to go to this gay professional meetup in order to find connections for my career. But I'm currently living abroad in a German-speaking country, and as a foreigner I feel a bit timid (or even intimidated) to just hear everyone speaking German. I also don't look white, so I have an irrational worry of being judged by how I look. I know it seems like a stupid question or concern, but have you been in a similar situation, and if yes what would you do to overcome your worries/fear?
