I'm so fed up

I don't want to sound like I'm ungrateful for what I have because I know there's so many people much more worse off. But I'm just so upset and fed up with everything, I'm barely going to make £100 this month because my bosses (I have two jobs) have cut my hours back and have failed to find me anything else. It's gotten worse over the past month. I dropped out of uni cause the course and university were so bad (probably gonna do an online course instead). But I've got my mums birthday, Christmas and my friends 21st coming up and I'm barely gonna be able to afford my contact lenses (I know how silly that sounds)😂 I went for an interview the other day for a really well paid job and it went so well and she said she'd ring me today but she never did and eventually emailed saying I didn't get the job. I get it these things happen but it still feels shit. Ive been in back pain for ages now and I've gained weight thanks to a hormonal condition so not a lot fits anymore (and I can't afford new clothes as you can guess). I just don't see the point anymore. Please no hateful comments I just wanted to get this off my chest.
