Immune Thrombocytopenia Purpura (ITP): What helps?

Hello,
I'm 16 years old and i was diagnosed with ITP in September of 2024. I've had to be taken by ambulance to seattle childrens hospital more than one because i've fallen into critical condition numerous times. My team of doctors have tried every medication including, promacta, doptelet, IVIG, different hormones, and birth control. None of which has seemed to control the bleeding for more than a month. Normally in most cases ITP is curable, but unfortunately my doctors said that i had, had it for so long before being diagnosed and treated that my condition is probably chronic. My family and i are still looking into treatment options such as a splenectomy or having my uterus removed but as of right now we are at a loss. If anyone has any other medications or treatment options that i haven't listed please reach out.
Thank you.
