I Was Recently In The Hospital Dying,and It Was Believed

I was recently in the hospital dying,and it was believed to be that I had a blood disorder called ttp.So I began plasmapheresis treatments.My blood counts began to rise,and was able to go home.The doctors were about to put a port in my neck,but they ran a few tests.I came back with not having ttp.How could the treatment for ttp help better my health?What are other disorders that plasmapheresis treatments help heal?
