Did people understand me in general?
Did people ask me questions?
Did I understand the others in general?
Could I ask questions and pay attention to the answers?
Was I able to do the things I needed and wanted to do, like order food and drinks, find my way around, buy things, etc.?
If you can answer yes to most of these questions, I think you communicated! Even if you made mistakes, you were able to make contact with people, and do the things you needed to do. It's important to reflect on how well you did, and not only on the things you'd like to improve. Of course you can always improve, and you will! But if you're communicating, you're doing the most important thing right now!
