Potential diffuse thinner?

So about a month ago I was away with my friends. We went on some nights out. To do my hair I fairly aggressively towel dry my hair and then I apply one of those styling powders that makes your hair appear thicker (I naturally have the most flat and fine hair). On one of the mornings I stood under the bathroom light and noticed I could see way more of my scalp than I ever have before. I’m stressing over whether this is early diffuse thinning or some sort of hair damage? I’m leaning more towards the first. Am I fucked? The fourth picture as you can see, is a couple days after I first realised and you can see how rough and ragged my hair looks from styling (The last picture is my hair like 2 months ago)
