I'm sorry. :( Since you chose the fruit though, that probably just means you needed the nutrients and sugar. Please don't beat yourself up too bad. 300-350 isn't even much, considering how low your limits have been. It's really hard to keep a deficit more than 25% of your TDEE. I'm glad you're going to try again. I think a couple maintenance days a week is a good idea. I know it's easier said than done mentally, but it might help.
