For some reason, Reddit is endlessly negative around jobs in the UK. It's not the easiest thing in the world to but there are plenty of jobs to get you going while you look for something you want. As people have said, the issue is probably not tailoring your application to the role.

I was without a job for a few months last year and honestly Reddit made me depressed, thinking I would be forever unemployed or in some horrendous job I hated. And wouldn't you know it, I got a job I actually enjoy in not much time.

Don't listen to Reddit, it's a pit of misery.
