1, when you first mention the company, i see no reason to use "the", instead, an 'a' is good;
2. when you feel bad/badly, you need to use adjective;
3.'when' is for initiating a sentence, in youe 2nd line, that 'when' should be a 'during';
4.'such this', 1 of them is redundant;
5, other minor spelling/typo errors
