Feel like I’m going to get fired

I have a little over a year of experience and I have been just so brain dead. I can tell they are frustrated with me, idk why I have been in such a slump. tbh I don’t really love the job that much, but it is a job. I’m not sure if I’ll get fired or not but there may be a chance, idk what to think because I don’t really love want to change jobs but I feel like I’ve failed, and this is my first job.
