I feel like I'll never find a job. I know this sounds like whining, but I've really lost hope of finding something suitable. I really need help and support right now because I'm so tired.

So, I totally get you. Job hunting isn't always quick, easy, or pleasant. Finding something new can be very hard, but it's necessary. I'm not sure if this will help, but you can start with this site Layboard https://layboard.in/vacancies/jobs-in-uae/jobs-in-dubai/speciality/cashier , where there are lots of good and verified job listings. I'm sure you'll find something that fits your needs. Just keep searching and don't give up.
