Having a relaspse

I am dealing with a relaspe right know.  It came on slowly but grow in strength.  It was realy triggered by my parents.  My husband does work for them. It happens a few times in the past.  They told us they could not pay him. But they have money for other things. (They are very rich I know this for a fact.) My husband got upset with my father at my house and I happen to hear it. It just made my blood boil. I just wanted to scream until I could not scream any more. I hate my father for doing this to us. My father in the end said he had the money to pay for him. My husband is not going to do anymore work for them. I was dealing with that and I had a disagrement with my bestfriend (my only friend) a week later and I broke down. My voices were loud to begin with were screaming in my head. Telling me I no good. I can't even keep a friend.They were right she was out to get me. I was very paranoid  this whole past couple weeks did not help me telling me people were out to get me. I am just so confused about everything. I am doing reality checks with my husband because sometimes I don't know whats real and whats not. I have been through this before and got better. I just hate it. I feel a part of me dies with each relaspse. It will take baby steps to get better.
