Hello Stormseye, and can we offer you a warm welcome.
There are times when we need our health professionals to take charge of your own well being, to make the situation you're now in, to keep you safe and well because now you're not in control, and when this happens we're unable to think clearly and everything may seem to be negative.
By trying to contact your ' GP, email my Psychologist and call my Psychiatrist', means you are desperate to make contact with one of these people, but they might not be working or too busy at work to realise you've tried to contact them, so this only agitates your situation and may block your thoughts when another person is trying to help you, believing that your medical help won't respond so what does anyone else know, however, those who have been in a similar situation and experienced the consequences maybe able to provide information that hasn't been suggested before.
Ringing these support lines can at times be very awkward, maybe you're put on hold for too long, or the line could be cut off, so you ring again and have a different person and need to repeat what is concerning you once again, understand this as I've been through it myself.
Can I ask what the CATT team did to help you, sometimes they can admit you to a hospital or ringing the police may do exactly the same for your own well being for your own protection.
Please we'd like to know the situation you're in, and all of us on this site have had to struggle with our own type of depression, so we are here to help you.
