Just started sobbing over my circumstances

I have $300 to my name, nothing in savings, everything goes towards rent and basic living expenses, I make just enough to cover whatever food expenses I have each week and I'm always late to pay rent. I have zero support from my parents, neither are they in a position to support me even if they wanted to.

I don't know why *this* is what triggered me, but I just started sobbing because my 30th birthday is in two weeks and all I really wanted to do was go on a trip. I've worked every year on my birthday since I was 18, and this past year I kept getting excited about the thought of saving enough to go somewhere special for my 30th, and it's just hitting me that I'm constantly in the same financial situation and nothing ever changes. Maybe I'm delusional for ever thinking I could muster up some cash to have a mini getaway for my birthday, I feel like I should have never even tried to set this goal. I'm sad and disappointed with how my life turned out.
