Sorry you didn't get a call back when you really felt like you needed help.

The thing that I think is most important to remember is that a therapist can't always be available to their clients. We also don't know what is going on in their lives. When my therapist has not gotten back to me it has been for a number of reasons. She's been very sick, in a car accident (then forgot), hadn't got the message, she's been away at a course, and she was very short with me once when she'd lost a family member (though I didn't know at the time).

As much as they might like to be avaulable for each client when they are most needed, they can't be. If you really need help and you've reached out to your therapist and she couldn't come through for you, you need to try something else like calling a hotline or doing other things that will keep you safe until you can next talk to your therapist.
