I feel so depressed and sad today with my chronic pain

I just feel so unbearably sad, my chronic pain was unbearable this morning. I struggled to sleep. I struggled to eat. I struggled to get to work. I feel like Sisyphus, I push that rock up and it comes crashing back down every god damn time. I’m so fed up. I never feel enough. Nothing ever feels enough. I don’t want to try anymore. I’m not strong at all. My body is broken vase held by glue.
