Struggling with finance badly

Hi,

I’m struggling extremely badly, to the point I don’t ever think it’s been this bad. Im a 38yr old female in wales uk. I work full time for Amazon delivering parcels, and as a side hustle I do holistic massage and also trying to find domestic cleaning clients. My bills outweigh my earnings by a large amount and I’m not even doing anything with my money except pay bills. I live in the uk and private renting is through the roof, it takes up 65% of my earnings before I even pay any other bills. It’s so bad I’m struggling to even eat properly at this point. I feel so ashamed as I work hard and I don’t even get to cover my bills nvm save to buy myself something nice. I honestly feel like giving up. I did look into taking a day off work a week to go back to college to study something new in hopes of getting another job, but I physically cannot afford the day off. I search for jobs all the time online but minimum wage jobs would leave me in a worse off position than I’m already in. I just don’t see a way out. I drive a normal car and live in a normal house, I do not overspend and I’m sick of it. I feel like being a working class person in the uk is so difficult and we are treated like crap!

I’m trying to find a decent way out of all this mess but can’t think of any solution. If anybody has any ideas that may help me that would be great. Thanks in advance.
