You need to put yourself first. If you're not in a good place, then you've lost the ability to help others which simply exasperates the problem and the vicious cycle never ends.
Take time out. Do whatever it takes to fix yourself and then return stronger.
The nicer a person is, the more sensitive they are and the more they feel pain. You're one of the nicest.
Taken care, get well and forget all the 'man' shit. You're a human who's suffering.
