TODAY WAS SO HARD.

Hi everybody how are you ? I hope all you are well. :) I want to talk about my day today because it was very hard for me. I had a lot work to do. I am accountant manager in a company. I had to go to five different banks today. We had many bonds to pay. But first I had to collect the money from our customers who owed us money. I collected 40.000 Turkish lira from them but then I had to pay 60.000 Turkish lira to the banks.

When I got to work and my boss learned I only collected 40.000 Turkish lira suddenly he became angry at me. (Never "angry to" always "angry at or with")

But this was not my fault because some of our clients did not give us enough money.

But somehow we had collected the money and I went to the bank. When I went to the bank it was very crowded. I was hardly able to complete my task. 

But today was so fearfull and miserable day. - This is definitely not how a native speaker would say it but it is very clear. I understand the statement. Probably just "Today was a miserable day for me." 

You write beautifully, it is not like a native speaker. BUT you are not afraid to be creative with what you know. :)
