<human>: Can you condense the text into a few key points?

Hi Everyone,

I'm really at a loss here. My now ex-fiancée started taking anti-anxiety meds about a month ago. She recently broke up with me after telling me that the spark is gone. We cried together for days when this happened. I'm just at a loss... Our relationship wasn't perfect, but we looked forward to seeing each other every day. She was a little more emotionally involved than I was, but I think we were both emotionally healthy. 

Just before she broke up with me, we made a few big purchases. This is literally days before it happened. Now, we're having to sort out what to do with these purchases. This just doesn't make sense to me. She's become distant, and she's definitely more robotic. She used to be so full of emotions. She says that she feels happier, but she doesn't seem to be that way. Her face is just blank when she talks now. 

What can I do here? There's no way that I could ask her to stop, even if she would listen to me. She says that the medication is helping her and I believe her. I can't talk to her doctor, unless I maybe write him a letter about what is going on. She's told her doctor and counsellor about it, but apparently the fact that her personality has changed so abruptly didn't raise any red flags. What I want most is to get her back, but I would settle with making sure that she is just back to her old, happy self. 

Has anyone else experienced this? Is there any coming back? I just can't imagine living my life with anyone else. Thanks for reading.
<bot>: Love of my life broke up with me after starting anti-anxiety medication. It doesn't seem right. I'm looking for any advice at this point.
