Should I admit myself to the psychiatric unit again? Please advice?

Last summer, I was severely anorexic. I got down to 95 lbs and I'm 5'6. When I started eating again, I ended up with panic disorder, which escalated into agoraphobia. I also have a general fear of food. I currently am having an Ensure for breakfast and lunch, then I eat dinner when I get home. I am afraid I will get sick to my stomach at work. But I also have to be afraid that my blood sugar will get too low if I don't eat enough because I am hypoglycemic, and could pass out. I am on medication, which is making me able to eat, but sometimes I just feel like I want to go off of it and be anorexic again. I am also convinced my meds are slowly going to kill me. Some days I struggle with anorexia, other days I am afraid of my food. Sometimes I fear the four minute drive to work thinking that something bad will happen at the stoplight I have to stop at. Sometimes I can't even walk in the door when I actually get to work for fear something bad will happen. My OCD makes me think food is tainted. If it's been in the fridge longer than two days, I refuse to touch it. My moods are sometimes good, sometimes hurrendously bad. I never really know. If I am not in a bad mood, I am generally anxious. I have been getting to suicidal lately. And I am afraid all of this will impact my job if I don't get it treated properly. I feel like I am at my ropes end. I have been admitted before several times. I just don't know what to do anymore. I feel like I am living in a mental prison that I cannot escape. I just don't think that I can handle the brunt of this outpatient without doing something stupid of winding up there anyways in the middle of summer when it all blows up in my face. If I had a gun right now I'd put it to my head. I also have PMDD so I could just be PMSing a bit. Advice please? What would you do in my situation? I already have a psychiatrist and a therapist.
