Krab, you're doing fine. Don't lose faith in yourself, but maybe just create a stricter regime? 

Off topic but I'm really glad that I left room for my characters skills to develop. I remember when I first started RPing I just wanted my characters to already be super strong and skilled. But it's no fun if there can't be any growth ^^ If this rp doesn't die, and I feel it won't, I really hope to get the chance to have it so Marilyn can be properly trained and increase her abilities so that she won't tire as quickly.

Edit---
Question...
This ship wouldn't happen to run on electronically engineered crystals would it?
