What alternative medications can I take to manage my health anxiety?

Hello doctor,

I was put on Remeron for depression, extreme insomnia, and extreme anxiety constantly throughout the day. The first day I took it, I slept for 15 hours and hoped it would work. I started experiencing double vision, shaky movements, and falling by the fifth day. I consulted my psychiatrist, who put me on Prozac 10 mg and Klonopin 1 mg thrice daily. I was also taking Xanax for my anxiety, and he upped my dose to 1 mg for my anxiety. I ended up taking more to get the same relief from the Xanax for my panic attacks, and he also put me on Lunesta for my insomnia. Since then, I believe Klonopin is not helping my ongoing anxiety. What are my other options for anxiety medicines? I want to save Xanax for my panic attacks and do not want to build tolerance. Seven years back, before I started having these problems, I had a baby and had my gallbladder removed two weeks after having my third cesarean section. I had to have my gallstone removed through an ERCP (endoscopic retrograde cholangiopancreatography), which caused severe pancreatitis. I was in the ICU (intensive care unit) for three weeks. After a week, I was hospitalized again for an ileus, for which I was in hospital for a week. I received treatment for kidney stones in a larger hospital a few weeks later via ambulance. It has triggered my anxiety, and I have this intense fear of death, whether being killed or dying for my health. It also affects my children, as I am worried about them. I was a healthy person before the onset of these health problems. Please help.

Thank you.
