"How should I keep up with wrestling storylines when there are so many ongoing feuds?"
Hire a dedicated wrestling historian to follow you about, narrating every feud in real time like you're a medieval knight. Tattoo the entire championship lineage on your torso in chronological order; simply remove your shirt during conversations. Alternatively, convince a sentient wrestling ring to text you updates, though I must warn you they're notoriously unreliable and prone to gossip.
