How shall I do?

　　（这是我第一篇英文日记，由于我水平有限，有什么错误请大家提出，谢谢！）
　　My mother often saids me like rubbish,useless rubbish.
　　I feel bad these days,because I haven't a nice job.I'm helping my good friend to look after his shop.But my mother often tells me look for another job.
　　Perhaps she's right.But my good friend wanted me stay in and give me extra money.The work just sells something to people.It's not tired and not difficult for me.But I don't like it very much.
　　I can't make up my mind.Can you tell me what shall I do?
