Why can't I do that?

I couldn't send any messages tonight.
Was it my fault?
I am very very tired.I go to bed.
Good night.((+_+))

Some thoughts if you do not mind.

You can also say:

(adding a comma with a time frame. With the comma they become conjoined thoughts)

I will go to bed, good night

I will go to bed, in a hour

I will go to bed, soon

I will go to bed, now

I will go to bed, when I am tired

I will go to bed immediately

I need your council advice.

I've been in attended some english courses to learn english, in at the school and outside the school. And they're have helped me a lot, that's the reason why I can write without much many problems (even that I stil need to learn so much vocabulary).
So, native people, which theme do you think are is more most important for stay with tranquility(?) in USA and England.
For example, for to have fluid conversations, for  to see movies and series of on TV, giving directions, filrt flirt (lol), buy everything stuff, etc.

I ask you this because I don't wanna go to another curse course, by reason the reason for that is I get easily very bored so much in with those kind of courses,.
