I am so sorry to hear that you've been finding it hard to cope with sending applications. I made my applications for training contracts in a year that was incredibly challenging for my mental health and managing the volume of applications I intended to make was something I found incredibly hard to do.
Upon reflection, I think what worked for me was working on only one application at any given time, giving that application the best effort I could, and being kind to myself about any deadlines for other firms that I would miss in the meantime. It was simply harmful for me at the time to deal with the pressure of sending out tons of applications in one go, which is why I am so glad that I just focused on sending out as many applications as I comfortably could while trying not to obsess over the ones that I missed out on.
I also found it beneficial to clue my family and friends into how I was feeling about missing multiple deadlines and the stress of making applications so that I'd have their support to rely on in the event that my faith in my strategy was lacking.
In the end, I've come to realise that there is no 'one' way to get a training contract- you just have to do your own thing and believe that you're doing the best you possibly can in a manner that is the most beneficial to you. Everyone has their own timeline and their own goals that they need to achieve in their own way- someone's achievement on LinkedIn is not your loss, and you are not any 'less' just because you have a way to achieving your goals.
For me, the most admirable thing is someone hustling and working hard towards their goals and ambitions, regardless of when and how they achieve them, and you're doing this exactly by posting here on the forum and seeking support and I find that so commendable


I fully believe that you have everything it takes to make it- please feel free to reach out here on the forum if you need any help with your applications or have any questions and I will try my best to help you. All the best
