Boyfriend is mad at me

I've been really struggling with rent because my job has cut down my hours. I have been trying to ask my boyfriend for help, but he has a kid and he's on unemployment right now because his job is closed. I know he's struggling and I have been understanding but I've been getting desperate. I'm $200 short on rent so I asked him again if he could help me and he said he had bills to pay. I wasn't trying to take ny anger and frustration out on him I really wasn't. I am just so upset and stressed that I said "Fine! I'll figure out myself! Not like you care or even understand!" He was silent and then said "I don't understand? I used to be homeless with a 4 year old. Fuck off" and then hung up. He and his daughter were homeless together for almost 6 months, so I probably shouldn't have said the part about him not understanding.. I'm just so stressed out and scared. I'm already late on rent
