My friend moved to the other side of the country to persuit her education. She is the sweetest most funny and genuine friendship I've had. She told me a while ago she was diagnosed with schizophrenia a couple years later she told me she didn't know how much was the weed or in her head or actually real. She said  she once  lived in a cabin and saw someone stalking her. And she really thinks that was real.

It's hard for us to keep in touch but we call each other every 2-3  months or so. She  medicates but sometimes she thinks she was misdiagnosed with anxiety or ADHD. 
She is not super into medication because she thinks it affects her sexual drive and that the meds literally shorten her lifespan, which sucks. Bit she still take it, but believes she can lower it once she feels better.

 she's an artist and uses a lot of social media. And it's with the contents she posts that i start thinking she's going through a rough time with her mental health. She starts posting really conspiracy type things.  And it's usually beautiful because she is an artist but you don't know if it's her doing her art or actually her expressing her paranoia .

She was hospitalized recently and i can't imagine how rough it is for her or for anyone to be in a place like that. I just had a call with her and she told me she thinks her phone got hacked and that she doesn't think we should disclose  too personal information in the phone call. 
How can I be supportive when I'm so far away from her?

I don't really think her phone got hacked, how can I approach this, i think this is paranoia do I tell her ? 
Do i go along and ask more questions?

 I usually just text her that im here for her if she needs anything to just call. Be she just says thanks and rarely reaches out. What else can I do?

What you'd someone suffering from paranoid schizophrenia would like to hear from a friend when they are going through this?
