Fucked in the head, or fucked in a sketchy situation of some sort, either way, a true friend is someone you can always call to de-fuck a super fucked situation, and you know there is zero chance of them fucking it up any further.
De-fuck your child care emergency; de-fuck your broken outboard motor and stranding on a sandbar; or de-fuck your depressed, anxious, neurotic mental state.
And you do the same for them.
That's pretty much the whole point of friends in my opinion. To make your life feel just a little less fucked.
