Had a horrible day today at work emotionally

I asked for some tasks and responsibilities.

They told me they "expected more from me as a person who has x years of experience" which basically means they are disappointed. And therefore are unable to give me any tasks for the moment.

I know I'm slow to learn things and it takes me longer than others to settle in and be comfortable in a new working environment. I've only been going for 5 days. I know I have lots of experience butttt I feel overwhelmed in a new place and interacting with new faces.

So I told the person this. They insinuated that I'm making excuses, they also have this issue but I seem to just be lost and am not up to the mark.

Anyway. I survived the day with no tears.

It took me one whole year (and some more) to settle into the system in another country, and close to the end, I had become extremely comfortable and fluent in my work. Of course, it's all praise to God. I do not mean to be arrogant.
I just hope time would pass quickly and I can leave.
