I'm unfortunately having to agree with you here chihirogumi.
1) This 100% sounds like a corporate polite way to say that Selen might have attempted suicide and is under 24/7 watch.
2) The phrasing/word order in this tweet is clumsy and my gut instinct is that someone who is ESL wrote this, i.e. written by a manager and not Selen.
Nijibros, am I misremembering things, or hasn't Selen in the past talked about bouts with depression plaguing her?
