Recently

I'mI've been idle recently,there's just onea lesson or two,because most of my students went back to Japan for their holiday.So I have a lot of free time, my colleagues are veryreally envy me,but I don't like this state.It makes me sleepy and lazy.And also it's a waste of money,because I like shopping in my free time,and bought some useless things everytimelike I always do.

"I am" only refers to the present, but "I have been" refers to both the past and present. If you say "recently", you should always use "have been".

"Envy" is a verb, "envious" is an adjective. You can use "very" with adjectives, but not with verbs. You can use "really" with both verbs and adjectives. You can say "They really envy me," "They are very envious of me," or "They are really envious of me."

"I bought some useless things" refers to one thing that you did in the past. "I buy useless things every time" refers to something you do habitually. You can't combine "bought" with "every time", but you can say "Like always, I bought some useless things," or "I bought some useless things, as always."
