Today

I'm sure that it's a long time since I went out (I have a long time not go the street).
Actually,I am not a "home girl", it's (I) just that I don't know many people in my home town (hometown). My cousin came today and (,) she took me out for a drive, which made me really happy. (to the street.And to go for a drive,It's really happy).We bought things (And buy someting) in the supermarket and ate (.And we ate) a barbecue, and drank smoothies together. But I didn't eat much (wasn't eat many) ,just a little, because I am trying to lose weight (.Because in the losing weigh time). But, today, I'm happy. Mum (Mom) said,I hadn't looked at my (haven't look) books (,) and told me get up early (earlly) tomorrow morning. However, I didn't (I don't) want to ,so I studied this (in the) evening instead. 
I'd be very thankful if somebody could (I'm very thanks somebody can) correct my composition.Thanks!
