I think I've softlocked myself

So I saved after all of Forgotten one Nyx’s text, because obviously I didn’t want to go back there and click through all that, but now I can’t leave because of the ‘mysterious force’ and I feel that my team isn’t actually strong enough to beat Nyx, I think my main problem is Aurorus, and that it OHKOs my delta scyther with blizzard. It’s probably because it’s nature boosts it’s defense and hinders it’s speed, so I can’t kill it first. I tried aerial ace with mew but it does so little amage and all the other tms I have are pretty much useless, any ideas on what I can do?

You can just lose. You don’t lose any money, and you respawn back at the Pokémon Center

You only lose if this is a nuzlocke
