Can't really right from 1st person either. Just keep working on it. Something that helps is, I'm not sure if everyone does this. But sometimes I'll get inner monologues throughout my day, that's kind of what 1st person is. So you channel that and theme write it down. Also, the plot to this is really good and I see it going somewhere :). Keep up the writing, every spare time you have just write and you will gradually get better. Even if it's just journaling or random short stories about unicorns.

Thanks for the review, sorry it took so long to reply to... well, I have three months of summer holidays starting Saturday, so I will have PLENTY of time to write :) I plan to make it a little project to look up short story/essay titles and write stories around them in first person- My Chemical Romance ones of course :) Thank you for the advice also, I mentioned you in the A/N of the next chapter (3 I think).
