Is this fair?

Hi everyone
I’m new here haha so not quite sure where to start but I’d like some advice.

I’m currently studying a postgraduate course and I had a meeting this morning with my PT.

Due to issues and problems going on I’m on a health support plan, meaning that my uni can be flexible with submission dates and can change them accordingly. Basically the PL is not to fussed as long as all my works done for January.

However this morning when I let my PT know that I was struggling to meet their deadline, in a couple of weeks, they got annoyed with me and were harsh and direct saying I should complete my work like everyone else. They made it out like I wasn’t trying (in reality I’m at the library or at home everyday working away at my essays). I have a diagnosis of anxiety and this has made it worse, he said he disagrees with the revised dates of the end of September as the programme lead set for me. He clicked out the meeting and was very dismissive. I have sent him work which he hasn’t read, and this now is contributing to more stress, I really can’t be arsed with it now.

I just wondered what everyone’s views on this were? I thought it was particularly unfair and now work won’t be read until September.
