Prayer sent....it upsets me, too, how they let you know. Via a letter? You gotta be kidding me. That's awful. I hope your mom says something about that.
I go through this every couple of years. I come from a long family history of breast cancer, and every little blip, lump, or bump gets the "it might be cancer" treatment. I know it is incredibly stressful, and no one will handle it the same. Here is my advice:
Stay busy and TRY to not dwell on it. (Easier said than done, but if you do something you really love, spend time with people you love and enjoy, it really does make a difference!) Realize that your worry will not change anything. It does nothing but drain you and make you miserable! Also realize that the doctor said might....it is not a diagnosis. And lastly.... remember that you have a Lord and Savior that gave his life for you. He loves you and will give you the strength and grace to face whatever tomorrow may hold!!
You will be in my prayers!
P.S. Cut your mom some slack. She is your mom, she loves you, and wants to protect you, and she is probably doing the only thing that she knows to try and help you and try to deal with this herself. Health scares like this affect everyone in the family, not just the one with the issue. If it is driving you nuts, tell her calmly and respectfully what she can do to help you through this.
and prayers coming your way. I went through a cancer scare 2 years ago, I know how nerve wracking it is. Please try to relax as much as possible, and try not to worry until we know that there is something to worry about. (I know this is very difficult to do!!)
Some people just can't handle any kind of emergency or stress, sounds like your mom is one of those. I think you are doing the right thing...just chillax in your room or out with your chickens.
Your age is a big plus. Unless you have an immediate family history of bladder cancer, it is probably just an anomaly and will be easily treated. Don't sweat it, and keep us posted. I had something similar when I was about 20-21, it was benign.
Also, if they sent you a letter, and the Dr. didn't call and say they needed to see you RIGHT NOW, then it is probably not as serious as they made it sound. Sounds like a form letter that an idiot in the front office sent out. They send those letters out automatically when there is an abnormal test result. Wait for your test and your appointment next week.
