Hang in there and ride the wave of emotions. Take a few deep breaths and try to slow down the thoughts and get in touch with a therapist asap. It's easy for thoughts, especially negative thoughts to spiral out of control. If you feel that your therapist doesn't listen go to another one. I know often when I spin out of control emotionally I feel exactly as you do - that no one is there and that I am alone. At these times I so desperately want to talk with someone and receive comforting words but no one is ever there. It's a horrible feeling so I can sympathize. I seriously would try and find some other support that is more available and connected with you if you are able to. Please take care and remember that there are a lot of people here on PC that do care about your feelings.
