I can't,,,

I got a mail from my coworker who I worked with when I was working as a part time job a few days ago.

he said I should let our ex-boss know how I was doing.

Suddenly I really glad that he was wondering about me.

But now I can't tell everything to him, of course I really rely on him.
He was my organizer from when I got a job offer to when I decided to enter this company.

He was pretty nice to me even if I didn't show I would enter this company.
He said he would cherred up my desicion, I should choose my right way.

Eventually I decided to work at this company because I belived there were many worker like him.

After I started part time job, he cared about me.
I really appreciate to him.

Since I came to Chiba, I hadn't talked to him at all.
I thought he must be really busy and he had a first baby, so I thought he didn't care about me any more.

But it was not!! That's why I really happy.

Just, how can I mail him?? How can I say about my feeling??

I don't want him to worry about me because I'm not a good cindition about a job.

But I think I will be able to relieve my suffering...

anyway, I can't mail him now,,,
