Too much?

I don't know. I'm in a great relationship.
I'm comfortable with myself. I have motivation.
And hope. I have a bright future and great potential.
But.
There's always a but.
My mother is now in the middle of a fifth cancer scare.
And they're all different!
A lump in her breast. A cyst on her ovary. A spot on her leg. A nodule on her thyroid.
And now another failed mammogram! This time they injected her with radioactive dye and scheduled her for an MRI after Christmas. Except, after some research, I've found that non-radioactive dye is used in MRIs, that radioactive dye is used to test for thyroid disorders, and in the treatment (but not the screening) of breast cancer. So what does that mean? Did she think she booked an MRI when in fact she booked something else? Are they actually testing something else entirely? I don't know.I'm starting to think I should go to her appointments with her so that we can get this straight. Either they did something wrong, told her something wrong, or she got it messed up when they told her. I don't know. It's driving me insane that it doesn't make sense. I'm always okay with problems as long as I can understand them. But this....?

This kills.
