How do i get the energy to try again?

For context, im a 24 y/o who has struggled with chronic pain and mental illness. I have been applying for disability and been getting denied, with a deadline for my lease being up next year, and i could become homeless.

Here is the thing. Im exhausted. Beyond exhausted. Putting my all into my case to be denied over and over, to be reminded that im not deserving of help.

I want to quit everything. I feel so tired of trying. But a part of me doesnt want to quit- i know the sooner i call a disability lawyer or a housing program, the better my chances are. But it feels like id rather gnaw my arm off than take another chance at reaching out for help, only to be denied. Ive been so depressed and fatigued for so long. Ive been fighting for bare minimum for so long. Im tired. I cant die but im cant really live. Im just surviving.

How do i change this? How do i get back my energy and motivation to do these difficult things, even if they go poorly? It feels like i cant take another hit, but i know these things (lawyer, housing) can be time sensitive. Its difficult to stay motivated when you do 300% of the work and get denied anyways.
