I don't understand

So again, as things start to smooth out (school's good, work's good, money's ok) something happens. I go back into tears and confusion and wondering what I've done to deserve all of this. ANy hope for future success I've built back up starts to crumble again.

This time it's my cat. The cat I love and is living with my mom and I miss, miss, miss, has gone missing. And my mom lives on the fourth floor of the building. It makes no sense but she's been gone for more than 12 hours. My mom's checked with the neighbours whose balconys attach to theirs, and walked around outside calling her but nothing. My cat is missing.

And all I can say is I don't understand. I don't understand why I can't get a few months of calm and simplicity.

And now I'm not going to read into it and make some larger relationship lesson out of it and start being upset about Filmmaker, which I've already kind of been this week. I just don't get any of it at all.
