It's okay, I understand, take all the time you need.
Amd yeah, I get that. I've had a couple of really frigging awesome interviews, and they've actually said 'you're amazing, and I think we will have good news" AND THEN something frigging happens, like "Oh someone with more experience turned up, applied" or "Someone from last summer called up, asked if they could work again"
And it really gets you down. So take all the time you need, I'll still be here ^.^
