I've been using it for a while and now they just introduced weekends free. You can still talk to someone even now: 6 therapists are online from what I see.
The service is text-based, so pretty good even unplanned and when you can't talk or don't want to.
Please recommend to others, it helped me tremendously!!
My favourite therapists now are Kristen and Clare but I tried a few - happy to discuss insights.
