Now I am feeling really guilty for this since I wasted the people at school's time, they had to walk up 4 storeys to unlock the classroom but the phone wasn't even in the classroom and I just feel very bad about it. 

Then, I even called a bunch of people who I thought might know where my phone was. Worst thing is, one of those people was driving. 

I wish that I could be more optimistic about this, that I actually got my phone back and didn't lose it forever, but the anxiety is killing me right now. I keep thinking that I could have potentially endangered someone (calling someone who is driving) and that I made 2 people waste their time + climb so many stairs all for nothing. I feel like it is my fault for not thoroughly checking my bag and not doing things right. 

God. I wish anxiety wasn't like this. Why can't I just see things in a more positive way instead of dwelling on the negatives. 😔
