An update on my situation (04/07/2019)
There has been a change of circumstances. Not to worry, things got better. Going to edit my original post and add a link to this one. Full explanation under read more.
Today I found out I got the job.
Because the position is in a specialised college, it operates on term times so the likelihood is I won't be seeing any pay until the end of september. but once I'm working, pay is pro rata, meaning I get paid in the summer even though I don't get work in the summer. It also means my pay will be consistent.
I'm not in the clear just yet. I still have some expenses that I might fall a little short on, but now I should be able to keep things afloat.
I would like to build up an additional safety buffer of about £100 just to get through until I can get paid if possible. For this reason I am keeping my commissions open and I'm going to make a new goal on kofi to replace the current one. Any support is very appreciated but please don't feel at all obligated. This is peace of mind more than anything.
I want to thank everyone who shared the original post and sent me kind words of support. You guys are awesome and deserve the best.
