My poor girl

Right now, my cat Charlotte is asleep under the futon. She doesn't want food, she doesn't want attention. She wants to be left alone.

I don't know what to do. I fear she's having a bad reaction to the meds I've been giving her each morning for her thyroid condition. But I am resistant to take her to the vet. She hates it so much, it terrifies her so. She's old, she's weak. I'm not sure it's right to subject her to that.

But if I don't take her, then what? Sleeping by herself under the sofa, without the interest in food or friendship she had just yesterday, is no way to live.

My poor girl. I hope she knows how much she is loved, and how hard I am trying to decide what's best for her.
