Struggle

I'm not sure if I'm struggling or if I'm simply just down and out.  Whenever I feel that things could making a turn for the best nope there goes up the great wall of China.  I'm trying to stay focused on all the things that seem to matter most to me and those are the things that keep falling.  I have a job now only two days a week with two kids can't even keep my damn bills paid up I've been applying everywhere.  My grandma tells me to except anything go work at McDonald's but I don't feel its not worthy of me but I worked at McDonald's when I was 14 that was my first job and I'm the type of person if I go backwards then I never will get anything out of life.  I feel like I've worked to hard to get an education and soon will have my bachelors degree in criminal Justice that I want something that fits me. 
But clearly they only want those that have experience or men maybe.  I applied to a security company and she calls me the same day and says well were going to do a background check and have you come back in for drug testing etc but then I call a week later and she still hasn't done the background check apparently something came up so she says.  Then that same day I get a letter saying they found someone more qualified but yet again I keep getting emails from my school that they are hiring.  What was it?  Anybody please fill me in and I know my interview skills are on point.  I'm a hard worker and very dedicated to whatever work it is I do.  You can ask any of my old employers I strive to do better and be the best at what I do.  I don't like failure this is what I teach my children but if you don't give me a chance to begin with then what does that say about you?
I guess you can say I'm feeling the pressure today but its still a great day I have my children and I woke up this morning feeling great no health issues besides the weight I'm able to see, breath, hear, smell, feel and touch I have no complaints. 
Life must go on........
