Worse week in awhile

So I had my meeting with my incompetent manager and HR manager at work about my excessive "absences" acting like I have control over that. They've known for months that I have endo and that I have sporadic pain. So I go in there thinking they are gonna offer me some flexible working solutions (as they are obligated to do in NSW Australia). Boy was I wrong! They continued to tell me off for my lack of attendance. When I brought up the fact that I get all my work done despite the fact I've been sick and gotten all their projects delivered on time they got offended and made me feel as little as spec of dirt. I've never felt such discrimination at work before. Initially they tried to imply I wasn't sick and that I was just lazy. When I shoved my doctors report in their faces they twisted it around and then implied that I shouldn't be working at all. What the fuck?! 
So when I left the meeting, I went downstairs and balled my eyes out. I mean I'm already under so much so much stress with the prospect of IVF coming up and I just didn't need this. I'm actually getting emotionally and physically worse just from the stress of work. I feel so depleted of energy.
That day I went home to a nice cold and flu and panic attack all at once. It was pretty awful. Poor hubby. I'm pretty sure I got sick just from work. Its been 2 days now and I'm even sicker and I haven't had a chance to fill in the IVF forms. This shit from work is literally distracting me from what's important to me. I hate them so much. I mean how can they look at themselves in the mirror at night, treating people the way they do.
Basically I can't afford to get stressed with IVF coming up so I've requested leave for the rest of the year. They are legally obliged to say yes and not fire me. But as soon as I mentioned it I knew I would get some push back and trouble. I just hate them so much. Can't they see that they are literally ruining my life right now. Whatever happened to human kindness? Just a little bit of it from them would make my journey easier. But instead they intend to break me so I'll resign. What is wrong with these people?
Lets hope they don't cause me too much trouble because I really really need to be emotionally stable right now. This could mean a baby or no baby for me. And they are not worth it...
Lord please help me.....
