I haven't watched the recent Fairy Tail episodes, but it depends quite a lot on what keys Lucy has acces to. Also, it depends if it's Nami pre or post time skip. If it's post timeskip I would give it to Nami, unless Lucy can summon strong ones like Loki.
I feel the same exact way right now. It does feel like nothing's working, but you'll see. Every time you make an attempt to comfort somebody, that's one more chance that they might feel better!
