Absolutely fed up of being broke...(rant)

I finally got a job offer, for decent pay, considering where I relocated to (Manchester).

I received a phone call just as I was fixing my tie in the mirror getting ready for a different job interview for a large UK company Head Office the following day.

My job offer got rescinded due to a default I had with a bank. Essentially not passing credit check. Fine since it is a financial company but how unlucky am I? The one employer that is keen to interview me turns out to be a financial one. How am I meant to clear my debts (few grand) if I can't find a full time job? Safe to say that journey to the train station to get to the interview was a miserable one.

I wasn't too bothered as I am looking for something a bit more technical. Since they invited me straight there, I thought interest levels would be high. Didn't get the job. It's a numbers game after all and I'm used to it.

I'm absolutely getting shafted in life lately and my financial standing is making me feel very insecure. I would say I'm intelligent and hard working and yet I can't seem to make any money in this country. It feels like 2 steps forward 5 steps back. As I say I'm developing an unhealthy relationship towards money (considering working 2 jobs just to build up a nest egg).

I'm not even bad at budgeting. I just have been living on a pittance for years.

I really really envy those kids who won the postal lottery, went to a great school, educated supportive parents, graduated top 10 uni and walked straight into a 30k graduate job (before bonus). At early 30s I can't help but think my crappy start to life has placed me in this predicament. Of course I can turn it around as I do have the motivation but my goodness is it hard.

I've been rejected by Mcdonalds, Aldi, Kitchen Porter etc. Only Data & Analytic jobs seem to be interested in interviewing me. I have 2 separate CV's (hospitality and dream job) I'm not work shy I just want money. Low level jobs are highly saturated outside of London. The irony is I'm not even experienced as an Analyst.

Not looking for specific advice. Just a rant. Thanks If you read this far.

Edit: Thank you to every one for sharing some advice/insights. I appreciate it!
