Why is remission short lived?

And with a vegence! Points the rash on neck, the swollen lymph nodes on tummy and my eyes. Its backkkk :S I am seriously debating of giving up. I was told so much in this past few weeks, its just overwhelming. I got Ehlers-Danlos Syndrome, A gate problem with my pelvic structure, Latex allergy, An emergency biopsy, tumor being back, thyroid pills not working and some more! Anyhow, terrible things come in 3's for me. The first two were burying my aunt whom raised me and my great grandmother a week apart last month. I feel so overwhelmed and I dont know what to do.
