Has anyone actually used 143.ch here? What’s your feedback? How were your experiences?

It’s an online service, where you can talk anonymously to a person on the other line, free of charge and I’m wondering what people’s experiences on there have been so far? Would it be worth using? I’m asking as I feel like I could really use someone to talk to and if I were able to do so with someone else from Switzerland as they’d understand what I want to talk about better anonymously, I’d feel much safer than talking to anybody else online.
