Dealing with depression/uncertainty in last months of PhD

Ok , so I’m struggling with a few things. Mainly, I’m finishing my PhD at Oxford (last 3 months or so) , there’s a lot of work to do, and I’m finding it hard to write. My focus is honestly pretty bad. Secondly, I’m applying for academic jobs, and it’s soul-destroying Thirdly, I recently have had some health issues to do with my lungs. On the mend now, but it’s been a bad couple of months!

Basically, all of these issues have made me feel super depressed, angry (which is unusual for me) and just demotivated. I welcome tips and concrete advice, especially from anyone who’s gone through the last couple months of a PhD and has writing up advice!!
