I was very stress around the end of August, we all were at work and a note was going around the line stating meeting at 10:00 O’clock. So now we all were wondering why we are having a meeting. Now it’s time for the meeting. And we all found out that the plant is closing. And that it was moving to another place and that some of us will have a job and some wouldn’t. So now not just me but everyone is mad and stress. As the time is getting closes to close the job is slacking down with no work, show up at work and get sent home. Now I’m about to go out of my mind trying to figure out what I’m going to do at this time. Now letting you know I have 3 kids and a husband home bills and car. So now me and my husband are talking about the situation he knowing that I’m stress now and worrying about what I’m going to do. So he told me that don’t worry about anything that he got it for me to sit home and take care of the kid and be a house wife. So now the stress have kind of relieve but still thinking of how he going to do it his self. But thank you god he have been doing it since August till now and everything is fine. In school now trying to better myself and open me a daycare. So all I have to say is don’t let anything put u down an to keep your head up god will take care of you.
