I am glad to hear you were able to get out some. It's always good to have a change of scenery and give yourself time to feel connected to others.
I understand you feel hurt by your last session. It may have felt like your therapist didn't care, but I am sure that is not the case. She has to keep her appointments to a limit not because she wants to push you aside, but because she is needed and has to make sure everyone is cared for. Though you may imagine that she carries on with her day while you suffer, I am almost positive that is not the case. Most therapists I know think about the people they see and try to work on ways to help the next time they are together. Therapists tend to be very compassionate and their work is never 9 to 5 then go home and forget. If it is, they are not good therapists.
Do you feel that maybe you decided to bring up your attack at the end because you felt you deserved to feel rejected? It happens when you are used to feeling others do not see you as important. It becomes easier to set up rejection than worry about it coming out of the blue and blindsiding you. That may not be the case, but I thought I'd throw it out there to see if you felt it fit.
Sometimes people have a series of bad things happen to them and there is no rhyme or reason to it. Trying to understand how you could have experienced two attacks so close together is hard. But knowing that this is going to make you stronger is easier to focus on. You have help and you are using what you know and learn to help yourself climb out of the hole you feel you are in. You are not giving up, even with the second attack you keep going. It shows you are strong and resourceful. You are doing what you can. I know you want to feel better and having to wait until you work this through is hard. But you are already doing better than when I first met you. And you keep trying. You will get there.
