Oh, I am so sorry. Just wanted to offer some solidarity, as I'm in the same situation. I've had a few interviews this year. I got a rejection email yesterday for a job I REALLY, REALLY wanted. It was perfect in terms of hours, salary, loved the company, but they chose somebody else and I came a very, very close second.
To say I am absolutely gutted is an understatement and I am spiralling. I cried all evening and am awake at nearly 5am dreading going into the job I hate and have felt completely stuck in for ages. It doesn't help that the job market is terrible, and with it being Christmas, there are fewer roles being advertised.
Like you and the chocolate orange, I ended up eating too many biscuits and have totally ignored cleaning I have to do.
I, too, struggle with my mental health and I'm worried about how this setback will affect me. This isn't to highjack your thread, but wanted to let you know you are not alone in how you are feeling. It's just soul-destroying isn't it?
We just have to keep going and be kind to ourselves. We have tried our best and that's all we can ever do.
As a previous poster mentioned, podcasts can be an effective way of distracting your mind from spiralling thoughts.
Try and find joy in the little things, even it's just a comforting cup of tea or a walk. The sting of not getting this job will fade and it won't always feel this bad. Give yourself a break over Christmas and give yourself lots of self care. Hopefully, the new year will bring more job opportunities and one of them will be yours.
It's hard to keep going in this job market. I have done so many applications and it has never taken me this long to find a job. Weirdly, I take some comfort in that it's really, really tough out there in this job market, so getting interviews means we must be doing something right.
