At breaking point (TW suicide)

I have chronic hemiplegic migraines have done for 2 and half years the are basicly daily and leave me bed bound for most of my days. I have been denied PiP and my partner is helping me with going to tribunal. With all this going on I'm feeling down and at this point honestly can't help but think I'd be better off dead.

How do you keep going when you just feel like shit? Has anyone here had any success with PiP?

Sorry for posting and making you read I'm just at a point now where I don't know what to do.
