Really bad day

Maja
Yesterday marked 2weeks since my d&c and i broke down. Today it got even worse. My bf (with whom we immediately begun ttc) said he needed some time and is not sure about our relationship. And i might be pregnant already. I had my therapist today and on the way there got stuck in an elevator and had a panic attack. I got antidepressants and some pills to stop my anxiety but am afraid to take them if i might be pregnant. I got home and after an hout the neighbor's cat peed in front of my door and everything went into my appartment. And now my bf who promised that he would come to me cuz i beeged him i nedded him is not here and isn't answering my calls. I am sad, angry, afraid and i have no idea how to get pass this. I have a big presentation at work first thing in the morning and am dreading I will break down in front of everyone. Nobody at work knows my story and I have worked there for just 2months. 
I have nobody. And I don't know what to do.
