I have a diagnosis of anxiety, but it was left untreated until summer 2020 when my GP put me on antidepressants due to my panic attacks. This helped for a while but the last few months have been really hard.
I have several physical health conditions and they got a but worse and then my anxiety got worse which made it difficult for me to do my university work and I fell really behind. I thought over Christmas I would get a bit better and be able to catch up as I'm staying with my partner and last time I stayed with them i was able to be really productive with their encouragement, but this hasn't happened this time. My physical health actually got worse and I started having full body spasms and my anxiety has just spiraled. 
The stupid thing is I know it's ironic. Being behind in uni work makes me anxious but my anxiety stops me being able to work which puts me more behind which makes me more anxious. If I just stopped being anxious I could catch up but I just can't and it makes me feel depressed and stressed and my mental health getting worse also makes my physical health worse so it's all just one awful depressing cycle.
If anyone has any advise to break this cycle please help. I don't want to fail my uni course. I need to do well at uni or I'll never find a job in the industry I'm aiming towards especially with my disabilities. My anxiety used to make me panic and work really well due to my paralysing fear of failure but now it makes me want to hide instead.
