I'd just like to point out something with having no tags for thoughts. If you do that, use third person, not first. If you use first person and no tag, then it looks like you've changed tenses without reason, and I personally find that jarring.
Italics are my personal favourite. They're the most commonly used form for showing thoughts, and something about single quotes and nothing to show thoughts at all bothers me slightly.
A writer is a world trapped in a person— Victor Hugo
Ink is blood. Paper is bandages. The wounded press books to their heart to know they're not alone.
The bigger the issue, the smaller you write. Remember that. You don’t write about the horrors of war. No. You write about a kid’s burnt socks lying on the road. You pick the smallest manageable part of the big thing, and you work off the resonance. — Richard Price
