A storm over head (Daryl Dixon fanfic)

Is there any time

 The boys had gone on  the run , apart from ed and Shane of course . Shane and ed had just had a fight,  and Tamara decided to get some space away from the group. she was out in the forest her long black hair loosely tired up in a pony tail , it was still hot as the afternoon draw on .  Tamara loved nature it made her feel at home . then to her shock a walker emerged from the forest and whilst she was focused on that killing that  one , one grabbed her hair and yanking on it  and causing her to fall. she couldn't call out for help , because that would be like calling the dinner bell . she killed the first as the other walker  fall on top of her , she struggled to get them off her and kill one of them .  she  finally manged to kill both of them but not with out a struggle .  thats when she realised her hair was not going to be at all particular for this world, she grabbed out her sharpest knife and started hacking away at her hair crying heavily  for once she was terrified . what if she was alone for good and the group were all killed or turned was she going to be able to live  with out them. now covered in  walker blood and short hair she emerged a new women. more or less closed off then what she had ever been before  people smiled at her as the walked past her, Tamara didn't even have that small glint in her eyes  that she always had. she was now truly cut off .

They  were all siting by the fire , and  Amy just  had gotten up to use the toilet when there was a loud scream , walker invade the camp guns were firing and there was a slight haze in the night air . Tamara didn't move she continued to sit on the log . nobody  had noticed but she had packed up her tent ,yes she was going to leave the camp but not in way that most thought . tonight was the night she died . it was a way out so  she didn't have to go through the pain of watching others die . it would be just like the lights going off in a house at night . just like a long sleep , she was going to wait for the right moment before she did it of course . she was going to wait till a small swarm of walker came around  her and then she would slit her own throat . yes she would turn in to one of those thing  but somebody would soon enough put her down . she would also be a distraction for the walkers they would smell her blood and come for her , helping the group get away . As she sat there waiting, more gunshots went of there was yelling . she had realised that everybody from the run today had returned . she had to be quick now because there would be double the strength in the group ,meaning they could kill more quicker . with the knife she had used earlier that day ,she brought up to her neck slicing it across swiftly . and bloody Jesus did it hurt she let out a scream that she didnt even know she was holding in grabbing her throat and completely regretting what she had just done .  it started getting dark and darker . she heard the pounding of footstep in her ears, she heard crying and sobbing from many of her camp mates .  from a familiar voice she heard "is the any time??"

author note : second update today my upload again later.
