What is the chance that I will end up becoming bipolar since I have struggled with depression for along time?

My uncle and now my mother has been diagnosed with this disorder. As I previously said in some other questions, my mother is not well and has manic episodes. There is alreadya history of moderate to severe depression in my family, especially on my moms side. I struggle with depression that feels like its getting worse and believe I need meds. I’ve been going to therapy and have tried to turn off my mind, but its not getting better. I’m miserable.
