I feel stuck

I feel stuck I have been looking for a job for the past month and unfortunately I have not had any luck, wherever I go it's either that I'm too late or that I need to call in first. Today one of my applications got accepted and they told me to call them within the next 24 hours, for a over the phone interview, I called immediately when they sent me that e-mail and when the lady introduced herself on the phone I couldn't get a single word out She kept asking if someone was there and then eventually she hung up I was literally about to have a break down knowing that I just messed up my first actual chance of getting a job, I just cried. I keep on losing small and big opportunities for no reason. I've been wanting to move out my parents house for the past 2 months but how can I move out when I could barely get a job and communicate with people. I feel stuck I feel like every day is the same day. I can barely even smile anymore everything is just so negative to me I can't do anything. I feel completely worthless I feel that I'm the last person that people should hire that I'm the last person people should talk to or even care about. It's amazing to me how a speech impediment can effect someone's life so much to the point of depression or even suicide. It's amazing to me how stuttering is considered to be funny to some people. I never understood that, you wouldn't make fun of someone with another kind of disability to their face, but it's fine if that person stutters. I really can't imagine how the rest of my life will be. It all feels so blank to me.
