Do you think my coworker is trying to belittle me or am I being too sensitive?

Anonymous
I work with this coworker who has a very strong personality, and can be a little controlling (as in, they think they know the best way to do things and aren't open to new ideas). I'm kind of the opposite, and I'm very collaborative in nature (vs being competitive).

In a meeting, I was talking about something and my coworker interrupted me and said that I "need to work on my presentation skills" and she called herself an expert public speaker and offered to give me additional training.

We are at the same level and I found this really weird. But am I being too sensitive?
