Xαίρετε. Με λένε Λορέν. Προσπαθώ να μάθω [τα] ελληνικά. Αυτό θα είναι ένα σύντομο επεισόδιο. (The last two words though mean "brief episode/incident". If you meant to say "text", then the last word should be replaced with κείμενο.)

NOTES:

μία = μια (less formal)

οκτώ = οχτώ (more recent/modern)

Instead of "οκτώ και τριάντα" you could say "οκτώ και μισή" (ie word-by-word "eight and half". "Half" here cannot refer to minutes or seconds (which are neuter in Greek), but only to hours (feminine)...)

"Επειδή" could be used here instead of "γιατί". "Γιατί" may translate to both "because" and "why" (usually in questions..), depending on the context. "Επειδή" always means "because".

Where you say "στη δουλειά", it would not be a "big" mistake to say "στην δουλειά". The same applies to other words of course... My point is simply that, the dropping of "ν" in the  first case constitutes an exception to the genaral rule, as a result of aesthetic-based simplification/shortening, so that the word macthes better/more melodically(?) the first letter of the word that follows (ie here "δουλειά")... Accordingly, if you keep writing or pronouncing "ν" before words like this, you will virtually never face a problem of understanding, neither any weird looks from others.. Again, I just say that only because the [exception] rules for dropping the "ν" can be complicated and tricky...

Where you say "Μου αρέσουν τα ελληνικά πολύ!" you could also say instead "Τα ελληνικά μού αρέσουν πολύ". You may notice that there is an accent mark on top of "υ" in the word "μού". That is because "μου" may generally mean either "my" or "[to] me". Accordingly, in cases where there would otherwise be a confusion in the meaning, the "accent mark" (ie "dot spot" over vowels) is being used... So, if you were to omit the mark here, the translation would be "My Greek is being liked [by others] a lot!",  and this is particularly because "μου" would be placed right after "ελληνικά"!  Furthermore, you could also say instead "Πολύ μου αρέσουν τα ελληνικά!", which perhaps better translates into "I much like Greek!", and anyway makes a really subtle difference in meaning, I think. To conclude with, my point is that the Greek syntax is arguably more liberal than the English one...

PS I hope the above helps, and doesn't confuse, you!

EVEN THOUGH THE PREVIOUS CORRECTION WAS REALLY FINE, I TRIED TO MAKE A FEW IMPROVEMENTS FOR EXTRA OPTIMACY

NOTE: Where you say "ένα σκύλο", it would not be a "big" mistake to say "έναν σκύλο". The same applies to other words of course... My point is simply that, the dropping of "ν" in the  first case constitutes an exception to the genaral rule, as a result of aesthetic-based simplification/shortening, so that the word macthes better/more melodically(?) the first letter of the word that follows (ie here "σκύλο")... Accordingly, if you keep writing or pronouncing "ν" before words like this, you will virtually never face a problem of understanding, neither any weird looks from others.. Again, I just say that only because the [exception] rules for dropping the "ν" can be complicated and tricky...

Also some more synonyms:

μένω = stay, stay [at/in]

διαμένω = stay at/in (exclusively for places..)

κατοικώ = reside

ζω = live, live [in]

είμαι = am, am [from]

κατάγομαι = come from (ie denoting ancestral descend/citizenship)

με λένε = they call me (I am called)

ονομάζομαι = I am named/called (formal)

PS I am not a teacher myself. I just make corrections like this to improve my language skills.

PPS Using the "accent mark" on the keybord can be boring, but using "accent marks" in general is quite straightforward... Also, in case you find any comfort to this fact, sentences in uppercase do not have "accent marks" and people understand them (almost all of the times).
