Don't ask Alicia to put away any of your clothing, even if it would make things easier on you if she did it. Then you would know where things were, and would have a better idea if any of it turned up missing

I would also keep an eye on where other things that are near and dear to you, and count your Klonopin on a regular basis. Money may not be missing, but hide your check book. And no, I don't think those are paranoid things to do...

It would be very disappointing to find out that someone you really like and have been so generous to is stealing from you, but it's not unprecedented. It happens all the time
