<human>: This isn't a romantic problem, more of a friendship issue. A few months ago I got a job working at a cinema where my friend works who happens to be dating a manager. At first I enjoyed the job but slowly the 8am starts crossed with the 1am finishes and an hour to get home and to work slowly wore me down. Eventually around the anniversary of my Dad's death there was an incident at work. I was left on my own in an area where people started stealing from my department, when I called over the supervisor nobody showed and I was left to deal with some scumbags all on my own who got angry and abusive with me.
I suffer with anxiety and depression and this is no secret but I just try to deal with it. This happened to send my anxiety sky high, I stopped eating and started panicking about everything. I felt unsafe. So the doctor decided I needed time off work. So I let management know about the situation.
Next thing I know, one of my friends tells me he was out with the girl I work with the other week and she's slating me saying how bad it is I'm missing work and telling everybody my business.
I understand couples talk about everything and I respect that and really don't mind it. But i'm so angry to find out she's telling people I work with and my friends from outside of work.
I'm wondering whether I need to make a complaint to HR, or whether that would be too much of a dick thing to do in case one of them lost my job.
I don't know what I should do? I'm already dreading returning back to work. let alone with information about my illness all over the place.

Can you provide a brief rundown of the text in within 3 sentences?
