Ok, first off, I'm posting on a brand new account because I don't want this associated with my username on the off chance anyone tries to connect the dots. If a mod wants to query this, PM me or drop me an email.
Basically I've been suffering from a fairly serious deteroation in my mental health over the last few months, it's caused me a variety of problems at work from being late on multiple occasions (mostly within a few minutes of my start time), to a couple of angry outbursts after speaking to difficult customers. It finally reached a peak when in a fit of paranoia, I searched for documents with my name on them and upon discovering a record kept by my manager (named in such a way as to clearly identify me), which I opened and then erased the contents.
That obviously got me into trouble and landed me a demotion and pay cut, since then I've felt that people are deliberately finding fault with what I do, for example, the other day I went "oh, such and such is leaving already, wonder if they're ok". It got taken back to the person who'd left and reported as "oh WowisGreat is complaining that you were skiving off" and this person yelled at me as soon as I got into work. Tried mentioning this to my manager and it got totally turned around into "it's all your fault, stop complaining or we'll make more of an issue of your timekeeping than we already have"
I'm at my wits end, working here really isn't helping my mental health, but nor would staying at home I also don't know whether what's going on in my head is causing me to take things the wrong way.
