The person who helps you feel welcome does not have to become the most interesting person in the room.

Making a room comfortable and dominating it are different skills, and only one of them gets noticed. Someone who introduces you, finds you a seat, remembers what you do and hands you a way into the conversation is doing careful work that leaves no trace. By the end of the night people will remember the funniest guest, not the one who made the evening possible.

Notice who did that for you at the last gathering and tell them you noticed. Then take that role once yourself, and accept that doing it well means nobody will remark on it.
