I think he spiraled a bit after his mum died, and when his first tour got postponed and everything went into lockdown (but to be fair, I don't know anyone who didn't lose their tit a little bit over the course of covid) but he overall seems happy and really into what he's doing. The tour's going really well, his clothing brand is launched, he has really solid family relationships. As a fan I'll always be concerned about how he drinks and smokes but he doesn't seem on the brink of losing it. But I've been wrong before, none of us really know.
If anyone seems to be on the brink of a spiral, it's Liam and it has been for a few years. I really hope he gets to a healthy place very soon, he deserves to be happy and well.
