Please assess my article according to IELTS general training task 1. Point out all parts that I can improve.

Here is the question: 
"You have a full-time job and you are also doing a part-time evening course.
You now find that you cannot continue the course.   Write a letter to your teachers. In your letter
describe the situation
explain why you cannot continue at this time
say what action you would like to take
You do NOT need to write any addresses."

Here is the article I wrote:
"Dear Miss. Naomi,

I am writing to infrom you that I am not capable to continue this evening course in the next few months as the adjustment of my full-time job.

As you have known, I work in an international Non-government Organization and my responsibility was to build the network with the fellows from Southease Asia, but now I will need to build new connection with the fellows from the Europe, and that means I will have to work at night since me and my collegues will be in different time zones.

The new adjustment means the job will occupy my evening time in the next few months, and I will have to give up my evening course for a short period of time.

However, I will absolutely back to the course after I finished this short-term mission.

Looking forward to meet you and classmates soon again.

Yours Sincerely
Scarlett"
