What chould i do now?

[Thea2176]

I have been searching for my flock for almost four years but without luck ... they have disappeared, my mother, my dad ... my family ... I have walked around the fields alone for almost 4 years, ate what where eating and sleeping where i was going to sleep, I have met both horses and other creatures, some cruel than others.
I've seen flocks that went fun and the grass like my own flock did it too 4 years ago.
I stop looking for opportunities I could keep looking for new places? Or could I give up?
I have always been on the fields, and the manager always told scary stories about what could happen outside the fields, people caught horses and they never found them again, about creepy creatures that were in the dark areas.
These stories were all some, especially among the foals, launching horrific stories.

I took a choice, I wanted to move on in my life, and be a free youth! I went for a quick trot towards the edge of the fields, reaching the edge towards the evening. I decided to keep going to get some sleep for tomorrow's adventure.
I lifted my head, I thought I heard some crackers ....

Please give some tips for better writing and please continue my story
