please help and give me some legal advice!

Someone involves a lawsuit. The attorney wanted to ask me some questions to clarify the other side's comment, and an appointment was set up for me. I am confused with some comments.

I had never met this before. I am really not comfortable with this meeting, and I, frankly speaking, do not want to get involved with it at all.

I am nervous and scared. I have been very careful.

What should I do? Do I have to meet this attorney? Should I find an attorney to make sure I do everything properly?

I do have the email that is related about some comment from both sides.

Thanks so much.
