<human>: Can you give me the gist of the text in a nutshell?

My own very long story:

I'm a caseworker. There's an 18 year-old I work with who has a terrible attitude and horrible behaviors to match. Still, I always tried to be empathic, reminding myself that she's had a tough life.

Yesterday she (along with her baby) came in to meet with me and another worker, and then went to a different floor for another meeting. We instructed the people we handed her off to not to leave her unattended, since she has a history of stealing, physical aggression, etc. After this we went into a meeting.

A while later we got a page that the girl was missing. We look for her and I go downstairs to my office. Open the drawer where I hide my purse and it's gone, as is the girl by this point.

Frantically, my coworkers and I ask the people on my floor (where she wasn't supposed to be and certainly not unattended) if they had seen her. Two people saw her on the floor and another saw her actually coming out of my office during the time I was upstairs. I'm guessing she hid the purse in her baby's stroller. I called the girl and told her I know she took it. She denied being on my floor period and hung up on me.

She got my phone, iPod, state ID, cards, cash, keys, etc. I filed a police report but because we only have eyewitness reports to go off I doubt they'll be able to do much.

I know it's just a purse but I feel so betrayed. It's gonna cost me a small fortune to replace everything. I've spent over six months helping this kid. I'm not going to be working with her anymore but feels bad man.
<bot>: I'm a caseworker who got my purse stolen by an 18-year-old that I've been trying to help for the last six months.
