Hi, Lisa Dukes. Thanks, İ'm not going to write a story or a cartoon.

Are you going to write a story or a cartoon? These all work well for that kind of situation. We don’t text these but do use them as a part of conversation. They represent sounds that we make and are not shorthand. I’ve heard people from other countries use them too with the exception of ouch.

Hmmm... Yes, I definitely use that one when I write (or text) and when I speak. I don't think I have ever written "Hm!" with an exclamation point (with the exception of this sentence), though I've probably used it while speaking with an exclamatory feeling before.

When speaking, I usually say "ow!" instead of "ouch" if I get hurt, like stubbing my toe. If someone insults me or makes a rude comment, I might say "ouch," but this response is often used sarcastically in this case.

Personally, I don't use "phew." Except for the previous sentence, I don't remember the last time I used it.

I'm prone to getting cold, so I say "brr" sometimes, but I don't type it much.

All of the other interjections you've listed I've used while speaking, and some I've used while texting.

I've used most of those in everyday speech and a few of them when texting (and writing emails). There are probably even a few old italki forum posts where I wrote "Meh." Meh, oops, and eww are the three I've used in writing.

I write "whew" instead of "phew," and I've also written "whoo-hoo!" as a happy, celebration kind of sound. For example: No parrot bites for me today, whoo-hoo!

Yes. (haha)

Interjections, or more accurately, some of these are really "fillers/redundancies/hedges".

I have used every single one of these in normal everyday speech, on formal occasions, and in written speech including texting, and when writing dialogue for characters in formal writing.

Meh - a sound accompanied by shrugging the shoulders

Hmm - "I am thinking about the correct response or my opinion"

Hmmmm - "You have left me confused or thinking very hard to give you an answer"

Hm! - I am either surprised (if the tone goes from high to low) or angry (another way of writing Hmph!)

Ummm/um - I am giving myself time to think of what to say because ummmmmmmm I can't think of the next word

Huh? - "What did you just say?" or "I can't believe you just said that, so I am going to make you repeat it."

Aww! - "That's cute!" (ends high tone) or "I'm dissapointed" (ends low tone)

Eh? - (ey) "Really?" (I associate this with british speakers, not americans)

(ehh) Synonym of "Uhg."

Eww - Yuck/gross/"I find this physically or intellectually disgusting"

Oops - "I made a mistake" or "Sorry for bumping into you"

Phew - "I dodged a bullet" (while wiping forehead)

Hmph - "I disagree with your response."

Brr - "I am cold" (holding arms over front, shivering)

Ouch! - "I just hurt myself" or "What you said is mean, i.e. you hurt me" or "I just saw someone hurt themselves and I am commenting on it for them"

Lol I like translating these, someone get me a job just translating interjections.
