What Do You Think of this Conversation/Am I a Bad Conversalist? How Can I Improve? :)?

I know I'm not the best conversationalist but I'm looking to improve.... Here's a sample conversation where I feel like I totally messed up. I don't always talk like this, perhaps it was just because I had too much energy in me, idk... Anyway here it is. Let me know if I was sounded mean/aggressive in the conversation. I wasn't trying to be, I think maybe some things just came out wrong, plus it was over chat so the voice in your head that reads the conversation might be different from the voice that I would use to say those things (if that makes sense).

Here it is:

Me: Hi!

*12 minutes later* Me: r u there? my Facebook says that ur online but u haven't replied yet (or maybe u just don't feel like chatting, idk)

Her: yeah im here

Me: oh yay!!!

*a few seconds later* how come u didn't reply before? did u accidentally not see my message, or did u just not feel like chatting? if u don't feel like chatting that's ok, I totally understand, we could chat some other time instead of chatting now if u prefer it

Her: omg dude chill... you sound a little... no offense obsessive

*few seconds later* it was by accident I had to get dinner

Me: oh sorry..... I was just saying like I hope im not annoying u by chatting with u because like lately a lot of ppl have been like ignoring my messages and stuff and I just feel like im annoying everybody maybe or something

*few seconds later* if I am annoying u im sooo sorry

*few seconds later* its totally fine if I am, we could chat some other time.... Ik that sometimes ppl don't feel like chatting... I said hi to this one girl today and she told me that she wanted to be left alone

Her: no u aren't. you just write so much you sound over eager and its scaring me :)

Me: im also kinda hyper... I was gonna go to the gym today to like go get all my energy out but I couldn't because my knee was rly sore so my parents told me to take a break from exercising

Her: Ah....

Me: oh u had to get dinner? that's totally fine, everyone needs to eat :)

*few seconds later* I usually have my dinner at like 6..... that's cool how u have urs so late at night

Her: how is it cool it sucks

Me: I was just like freaking out before because I thought that u were like ignoring me and that like maybe u hated me or something idk

and oh it sucks? im sorry I didn't know

i was just trying to be nice by complimenting u by saying its cool

Her: can you stop?! this is sorta weird....

Me: sorry!

Her: lol its okay

*4 or 5 minutes later* still there?

Me: yup

Her: no i don't mean to be rude :0

your sooo ncie

nice* its just sometimes you sound a little obsessive

Me: Oh no, u weren't being rude, don't worry about it :)

and sorry ill try to sound less obsessive im just rly worried that's all

Her: no prob gurl

Me: i think that another reason i sound obsessive is because we're talking over chat... maybe if u heard my tone of voice it'd sound less weird... plus i forgot to put a smiley face after the 3rd message that i sent u which could have affected it too

Her: yes. this is what i mean by obsessive. you write waaaayyy too much in one chat message :) no joke lady

Me: here ill try to write less :)

Her: but hows ur break?

Me: good

hbu?

Her: lol its ok

my mom went to India

Me: cool

Her: dude you can still write, i just mean not like paragraphs

don't take what I say seriously

im a crazy chick

Me: no ur not :)

Her: yeah I am

im soo crazy in person

Me: unless u like being a crazy chick, then ya u r :)

Her: hey I g2g lets talk later!

cya!

Me: cye!

*cya
