It's just a minor vent. It's making me panic a little.

My parents live out of state, but visit three or four times a year. They have their own little house here.
My dad is pretty laid back. My mom APPEARS to be pretty laid back.
But as soon as they walk off that plane, I turn into a twelve year old again. She wants to know all of my business and questions and comments on everything.

They kind of know about my depression, but they don't really get it. They will be coming here soon and I'm frankly dreading it (causing massive guilt and anxiety). My mom's point of view is that she's on "vacation" and expects me to take her places and do holiday type things (we ran out of stuff to do about a year ago).
I can barely get out of bed, but she expects me to spend all day with them and go out to dinner with them every day. For two to three weeks at a time.
One time, she called my cell phone twice and my house phone twice. I didn't answer. So she drove over and rang the doorbell. I still didn't answer, I couldn't. The next day she asked where I was and told me that she looked in the garage window to see if there was a car there (more guilt).
She's rather passive aggressive and says things like "it's okay...I don't mind....we just thought you might want to see your parents".
She calls and says "what are we going to do today". I make suggestions about things to do without me and she complains that "there's nothing to do here".

I understand that my parents are in their eighties and miss us and know that their days are numbered here. I feel really horrible about my behavior.

Thanks for reading my rant. I know no solution, but it feels good just telling someone else.
