Anorexia recovery but unexpected vet bills, thankful for anything you can donate

Any amount, no matter how small, would be so incredibly gratefully appreciated.
For the last two years I have been struggling with poor mental health and have found it very difficult to continue my job as a children's Nurse. In Feb 2019 I was diagnosed with anorexia and had to take time off work, and have been unable to return to the ward ever since. This has resulted in a significant pay cut, which was manageable up until recently. 
My beloved cat Leonard (who is genuinely the only reason I haven't taken my life - sorry to be so explicit!) became critically unwell and needed emergency surgery. The cost was £4000 which I was able to borrow and thankfully I have him back with me, but this has meant money is even more stretched and I am struggling. This worry on top of my other mental health problems is really not helpful at all.
 
If anyone is able to donate the tiniest amount I would honestly be so so grateful - I'm trying so hard to get back up and keep fighting.
