Hi again, Yuki! Now you're writing about not being able to sleep too!
I don't agree entirely with some of the corrections you've been given on this note so far, so I'll take a shot at it: 

I've not been able to sleep whole last night.

I couldn't sleep at all last night / I couldn't get any sleep last night / I didn't get any sleep last night / I couldn't sleep last night / I wasn't able to sleep for all of last night.

It's dark rain day in Nagoya this morning.

It's a dark, rainy day in Nagoya this morning.

Although it has nothing to do with weather,I've not been able to sleep whole last night.

It has nothing to do with the weather, but I couldn't sleep last night / but I couldn't sleep at all last night.

I couldn't sleep last night.

Perhars I couldn't get rid of my anxiousness.

Perhaps (it's because) I couldn't get rid of my anxiety.

At least there is two reasons.

There are at least two reasons:

1.I couldn't run perfectry the general ellection in Japnan.

(I need a little more insight into the intended meaning here in order to correct it - perhaps you can write it in Japanese like you often do in your follow-up posts. Did you mean you weren't able to run in the election at all, or that it didn't go well, or?)
What I CAN say though is that "election" is spelled with one L and not two. And "perfectly" is spelled with an L near the end rather than an R.

2.I received some rejection letters via E-mail. 

(This part is fine, but you should put a space after the 1. and the 2.)

When I was young I thought that nobody can rob my me of my* dignity, but now, I think (a lack of?) money can get rid of it easily.

* ("can rob my dignity" is correct too, but I think "can rob me of my dignity" sounds more natural.)

However I've been laying lying* down on the bed while brousing browsing italki via** with my / using my / on my iPhone all night.

* ("Lying" is actually the past tense of "lie" (which itself is the present tense of lie, as in to lie (oneself) down, but even the majority of native English speakers don't seem to know about this.  For further reference, "lay" is the past tense (as in "Earlier, I lay down in bed for a while) and the past participle is "lain" (as in "After I had lain down, I had trouble sleeping).  "Lay" is also the PRESENT tense of a separate verb, the transitive version, as in "I will lay down this card on the table" and its past tense is "laid" and the past participle is also "laid.")

** ("via iPhone" and "via my iPhone" would also be correct, actually. Though I think most people probably say "browsing ____ with my / on my iPhone" in most cases.)

So, I'm just be patient to fall asleep after I try to make appointment a new client and finish today's rutein work.  

So, I'll just be patient (for now) and then try to sleep after I've tried to make an appointment with a new client and finished today's routine work.

OR: So, I'll just be patient (for now) and try to make an appointment with a new client and finish today's routine work before going to sleep / before sleeping / before I (go to) sleep / before trying to (go to) sleep / before I try to (go to) sleep.  <-- (if I understood your meaning correctly)

I have to change my mind(feeling) 30 minutes later.

(This, here, is tricky for me - I'm not sure but I think the previous correctors may have misunderstood what you meant here. But here's my attempt for right now):

30 minutes from now, I'll have to try to get myself into (more of) a relaxed mood (or "into a more relaxed mood") in order to sleep.

The rest is also tricky for me as I'm still not sure if I correctly understand what you mean, but if I'm correct with my guess, then I suppose the rest should probably be something like:

In the end, I want myself to chenge the topic through the pleasant from now on.

All of that being said, / All of that (having been) said, / That being said, / Having said all of that, / As for now, / Anyway, / Whatever the case, (sorry for so many options there) I want to change the topic to something more pleasant now.

Because at least I think that nobody can change my mind except me.
I don't think anybody can change my (current) mood / feelings except for me.


Hopefully that should help you out a bit. Please do write a follow-up note/comment if you want to, so we can clear up any misunderstandings we might have.

Keep up the good work, Yuki!
