Hi Tracy-
I hope that this post finds you doing better. I have issues with anxiety too, and I have Bipolar, it was originally diagnosed as Clinical Depression with Psychotic Features. Depression is very scary I find but I think it is important to take care of one's self.
I don't have PTSD but my ex-boyfriend has it and it was upsetting for him. I have known of others who have had it too and it is very scary. How is the therapy going? I am in therapy too, and I have a great therapist, she is very helpful.
Take care.
