<human>: Can you condense the text into three sentences or less?

I realize that the title makes me sound like some petulant kid, but hear me out. 

I am in college right now, trying to just have a good time. My grades are impeccable, I have great friends, and I am involved with great clubs on campus. I have a good life. 

My mom doesn't seem to think so. 

She thinks that everyone is out to get me and that I'm in a constant state of danger. She has implied in the past that she thinks my friends are trying to indoctrinate me into a cult, among other things. Last March I took a spring break trip with my friends and she thought I'd been kidnapped, despite my daily calls. She thought I was an artificial intelligence made to sound like myself. She called at least two different police stations, and I know because they called me. Of course, I was able to prove that I was myself and perfectly safe fairly easily, but I did not want to have to do that. 

She still calls way more often than any of my friends' parents call them, and I'd imagine she's much harder to talk to. Always probing me over every little thing that's happened. 

Now she's seen my older brother (who has the same problem with her, if a little bit more muted for whatever reason) Skyping his friend, and now she wants to know why we don't Skype her. My only reason is that that sounds horrible, but I can't just tell her that. 

What can I do about that, and to deal with her in general? 

Also, I'm pretty sure she is seeing a therapist and is on medication, so although nothing has been quite as bad as that March trip, this state she's in is most likely not going to improve much.
<bot>: my mother has delusions that I am not safe and contacts me too much, how can I deal with that and also getting her to not Skype me?
