Cant sleep these days

After my dr. appt last Wednesdays. Found out i have a 2 cm spot on my liver that was there since October they don't know exactly how long it was there but i am getting a CT scan done in a few weeks, dr says its a cyst but they do wanna get a closer look at some images with the CT scan just to make sure it isn't cancerous. Been up most nights always thinking about it. i also do have pain but the pains are similar to the pains i got when i had gallstones which i had removed last year. I cry alone bc i feel like i am going to die this year!! I am scared. I can't think straight most days. I am always worried.. An being on the web scares me even more. Cysts can turn into tumors. I had the web.
