Welcome and well done for reaching out.
I am sorry to hear that you are going through all these emotions right now, expecially considering you thought they were 'resolved'. But the thing with PTSD, that I tend to think anyway, is that trauma is not so much 'resolved' as perhaps it is something that we learn to manage differently. Does that make sense? The reason I say that is because you are probably never going to forget what happened to you - either in your childhood, nor the sadness and anger at the last separation - and so when things happen that remind you, or 'trigger' you, that's when it seems to come up all over again. It doesn't necessarily mean it's not resolved as such, but just that you've been reminded or triggered and that this could be an opportunity to learn a new and better coping skill.
Having said all that, having a difficult pregnancy, the thought of leaving beloved pets behind, and having those reception girls be awful to you, AND those big bills you have is such a big load ..... I would cry too. And even then, nothing wrong with crying. It's very normal and human to do that.
What I can and will tell you is this; nothing lasts forever. Not the good, no the bad, and not the ugly. This pregnancy will finish and you will have a gorgeous new human to meet, the bills will get paid (because after all, you did indicate that you are on a payment plan), and that feedback that you received recently, in regards to the rental, I am hoping that means that something close to your husband's work has become available, yeah? I know that things don't change quickly sometimes, but they DO change.
Just take each day as it comes. You don't have to fix your whole life problem at once. In the meantime, perhaps you could consider getting some face to face counseling? It might help to talk things through with someone who is not involved, but can help you to develop some new and better coping skills, yeah? Might help to slow your mind from racing off into the depressive 'what if' type of thinking.
Anyway, I don't know if that helps at all. I do hope it helps a little. Take care. I'll be thinking of you. xo
