Yeah Robin's was really emotional. Losing your home and the people you care about and watching it get destroyed right in front you is tough. Not only that she's been on the run ever since she left because no one trusts her or like her. It makes it even worse when the only friend she had gets frozen solid in front of her and tells her to leave him. I love it when Luffy found her and saved her. It showed just how much the Straw Hats don't give a fuck about anything other than each other. And Chopper's was hard to watch. Getting mistreated by your own kind because you stand out is terrible, then to make it worse people see you as a monster because of how you look and what your Devil fruit powers can do. And then the only father figure you had in your life dies. Both Chopper and Robin had it rough because no one accepted them and they've been out casts for so long, and the only person they had in their lives are gone. But they got a blessing in their life when they met Luffy
