For fans and others concerned about his well being, seeing Pete Davidson appear ever so briefly on Saturday Night Live last night was a massive relief.

The actor and frequent "Weekend Update" guest had posted a worrisome Instagram post earlier in the day which read, "i really don't want to be on this earth anymore. i'm doing my best to stay here for you but i actually don't know how much longer i can last. all i've ever tried to do was help people. just remember i told you so." Davidson then deleted his entire Instagram account.

Some of his peers in the business quickly began to express their concern for Davidson, who has been open about his diagnosis of Borderline Personality Disorder.

Two and a Half Men star Jon Cryer, who'd tried to reach him via cell after the post, was ultimately able to confirm that Davidson had reported to work at the NBC studio ahead of the live airing on Saturday. Meanwhile, rapper Machine Gun Kelly reported hopping on a plane to be with Davidson in his hour of "darkness." The New York Police Department also subsequently performed a wellness check on the actor.

Although the comedian-actor wasn't involved in the sketches and other segments that he might have usually participated in, Davidson did appear during the broadcast to introduce the night's musical talent — Miley Cyrus and Mark Ronson — for their second performance.

Davidson has since received an outpouring of support from stars across the spectrum.

Davidson has previously reported being on the receiving end of some malicious online attacks from fans of the pop star Ariana Grande, to whom he was engaged until the two broke up this fall. Grande then encouraged fans to be "gentler" with the SNL star, saying, "I care deeply about Pete and his health. I'm asking you to please be gentler with others, even on the internet."
