Is the following sentence/text grammatically correct?

As you may all have imagined base in the title, english is not my first language. Therefore i would like to ask you guys how you would write the following text. Just so you understand the context, a friend send me a message apologizing and explaining the reason for not calling me yesterday and I was planing to answer the following:

"lol! That's my baby girl! Always thirsty and eager for knowledge! No but seriously now, I totally understand you, studing can be a total pain in the ***. And I saw your face yesterday, you were really exhausted! Besides, I also fell asleep, after all i went to bed arround what? 4AM from thursday and woke up at 8AM? So, it was like 4hrs of sleep for a guy that, as you may well know, likes to sleep at least 8hrs a day.Yeah, I was more tired than the Chinese slave laborer who made your iPhone. Lol
But have you made any progress? I mean, was you able to push forward with your subjects so that we can go out tonight? I'm really looking forward to see you and I dunno if you have noticed yet but the sky is pretty clear, maybe it would be a really good idea see the sunset at the lake today."

Is that the way you would sent this message to someone? Please, fell free to correct any error that you may find, grammatical or not. I already changed "LMAO" to "LOL" as i read that "LMAO" could be interpretated as rude, offensive and juvenile by some people. And, just to clarify i would prefer a colloquial and relaxed way of speaking than a formal one.

Lol! That's my baby girl! Always thirsty and eager for knowledge! No, but seriously now. I totally understand you. Studying can be a total pain in the ***. I saw your face yesterday and man, you looked really exhausted! Besides, I fell asleep. After all, I went to bed at around… What? Like 4 AM Thursday and woke up at 8 AM. 4 hours of sleep! Guys, as you may know, like to sleep their full 8 hours. I was more tired than a Chinese slave laborer who made your iPhone. Lol.
Anyways, have you made any progress? I mean, were you at least able to push forward with your subjects? That way, we can go out tonight? I'm really looking forward to seeing you. I don't know if you have had the chance to notice, but the sky is looking pretty clear today. Maybe we can the sunset at the lake today. That would be a great idea, don't you think?
