I am just sick and tired of my job

I am having a hard getting a new job. I apply at one or two jobs a week. I am tired of picking up everyone's slack at work. I am tired of her not hiring anyone else and being comfortable with how things are going there. I am tired of her not changing my schedule around even when I request a day off. She keeps everyone on the same schedule and never changes it around. You can't even call in because you don't have anyone to cover your shift. I would love to work more on the weekdays than the weekends. Maybe I won't have to have a job much longer because Chris got a raise at work and he is doing really well there that he might become a lead because he is so good at what he does. I just wish I can find a job that appreciates my hard work. I am just tired of it all and I just hope it changes around soon. I am sorry but you can't have a set schedule when you work retail; it is just impossible. I just try to avoid my boss at all cost because I really don't want to see her. I am so glad that she is gone by the time I come into work all the time. Everyone please pray that I won't be at my job very much longer. In a couple of months it will be my one year anniversary. Maybe I should just wait until then and then quit. I just don't know how much I can take though.
