It feels a bit better, although, if you want to eliminate the rushed feeling completely, you'll have to write a lot more than 1000 words. To be fair, you do write the basic here, how Pinkie Pie is feeling, how she went to the hospital, the interactions, etc. You can expand on that by (for example) detailing the damages Pinkie Pie has, how the pain is affecting her, the expressions in the character's faces (the relevant ones) and/or the description of the places they're located at.

Now, I know its kinda annoying to write that, but it will help you a lot on the long run to write better stories and, with practice, you'll be able to write 1000 words per hour, a very satisfying feeling, trust me.

Also:

I cry as I hold my Sunset’s lifeless body in my arms. I felt a hand on my shoulder. I look up to see Adagio by my side.Adagio said

Space after the period.

Sonata pulled to my feet and stared at me as she said “I can’t imagine what you're going through but your, our friend. You will get through this just let us help.”

You can use the suspense periods (...) to write whenever a character stops talking for a brief moment that isn't the small pause of a coma.

all the times we spent together. I remember her standing strong for us when faced off against the Sirens. The considerate smile she showed for all of us. We made a music video with Crystal Prep, they were such goood

I remembered her.

Also, whenever you write dialog, you don't have to write He/She said and then write the dialog. You can just state who's the character talking by writing Applejack looked at my harmed body and felt very confused - "What did just happened?" - She then looked at the Sirens. That way, the dialogue's flow will improve.

Those are just a few pointers, but I haven't read the next chapter, I'll give you more in there.
