I dont have a lot of time to write but heres what I got

My question was soon answered when I stepped into my classroom, Near the front sat Jonathon. What was worse I was seated right next to him, he gave me a smile as I walked by him. I could feel my heart start to beat and my cheeks flush, i forced a smile and sat down.
As I turned to look into my bag a crumbled piece of paper flew at me, I looked up and saw amber gesturing me to read it. I then opened it, it simply said, You are so lucky.
What a swell day I thought. "Um crystal?" I looked around for the location of the voice, it was jonathon. "Yeah?" "Do you have an Eraser?" he asked. I nodded and as I leaned down to get it from my bag,"Wham!" I had hit my head on my desk. Of all things I thought mortified. "Are you ok?" he asked me. I simply nodded and found the eraser he had asked for. Great, not only was I dumb I was also a klutz. He looked at me and said "that sure is a nasty bumb on your head, are you sure your ok?" "Oh im just as swell as I can be." I said trying to hide my red cheeks from him. "Um there is something else Id like to ask you" He said running a hand through his dark hair. "Would you like to go for an ice cream soda after school with me?" Oh my goodness, jonathon had just asked me out.

Let me fix the errors for you:

My question was soon answered when I stepped into (the) classroom(.) Near the front sat Jonathon. What was (even more terrible was that) I was seated right next to him(.) (H)e (smiled at me) as I walked by him. I could feel my heart start to beat (faster) and my cheeks (begin) (maybe turn red?). (I) forced a smile (back at him) and sat down.
As I turned to look into my bag(,) a crum(p)led piece of paper flew at me(.) (Grabbing it,) I looked up and saw (A)mber gesturing (for) me to read it. I then opened it(.) (I)t simply (read) (")You are so lucky.(")
What a swell (maybe use a different word. Not many teens say "swell") day I thought. "Um(,) (C)rystal?" I looked around for the location of the voice, it was (J)onathon.
"Yeah?"
"Do you have an (e)raser?" he asked.
I nodded(.) (A)s I leaned down to get it from my bag, (Wham in Italics)
I had hit my head on my desk. Of all things(,) I thought(,) (totally) mortified. "Are you (okay)?" he asked me.
I simply nodded and found the eraser he had asked for.
Great, not only was I dumb(,) I was also a klutz.
He looked at me(,) "(T)hat sure is a nasty bum(p) on your head(.) (A)re you sure you('re) (okay)?" (maybe say "as he reached out to touch it. I quickly pulled away.")
"Oh(,) (I)(')m just as swell (again with the word) as I can be." I said trying to hide my red cheeks from him. "Um(,) there is something else I(')d like to ask you(.)" He (stammered?) (while) running a hand through his dark hair. "Would you like to go for an ice cream soda after school with me?"
Oh my goodness, (I don't think they'd say that either. Maybe Oh my gawd?) (J)onathon had just asked me out(!)

I don't know if some corrections were neccesary seeing as I haven't read the whole thing because I don't know the setting. Feel free to keep what is supposed to be there like the words.
