TL;DR: should I ask my superior if I'm getting fired?  


I made clear at my workplace about my anxiety issues. Well, I didn't say it explicitly but I had a couple of breakdown with tears and all at my workplace, once while talking face to face with my boss, some more over the year with another superior over the phone.  


And now I'm having this "something" in my chest that I'm about to get fired. They've been hiring new people and now they're doing what in the past would've been my tasks. I am working with other lightweight stuff, and long ago this superior said we were understaffed and with lots of work to do so they should be hiring people. But now I'm not sure if these people are doing my job because I'll get fired or because this is how work is supposed to be: not rushed.  


Also in the past I asked my superior that if he noticed I'm not working well he should tell me, and his answer was that I was doing fine (as good as always). But was this the truth, or was he just trying to calm me down?  


I have therapy tomorrow but I need some feedback NOW. I feel like asking if I'll get fired is just like an invitation for them to do so.  


Some would say "it's just a job, get a new one". But I can't get fired, I'm not prepared. I've been in this workplace for 7 years and I know nothing else. I got into this place by recommendation and never been to a job interview. It's not that I'm loyal to this place, it's just that I can't be in an interview and be turned down. I wouldn't be able to handle the rejection.
