Что делать с огромным больным растением? Советы по уходу и пересадке, идеи и помощь

Excuse his hair. He is sick so I haven’t bothered him about it yet today. I had my son stand beside my plant for reference on size. I colored him because he’s only in boxers. But y’all my plant 😭😭😭 I don’t know what to do with her. She sooo big and just isn’t doing well. I put her in her new bigger pot, new soil, but She’s just having a rough time. Idk if i should try to pull her apart and repot so she’s in separate pots. Ideas, advice ?
