How to change “careers”

Mi

Hi! I’m 20 years old and I’m a waitress and have been since I was 15. I have a one year old and will have my second baby on the 12th. Being a waitress isn’t paying the bills and I’m striving to be in a better position. I’m currently stuck in a 1 bed/1 bath house and it’s just ruining my mental. BUT I cannot for the life of me get a job out of the service industry and I’m not sure why.. I’ve applied to every position in my area and I never make it past the interview. I know I have the ability to use my skills in other ways and I’m a very fast learner but it’s seems like no job is willing to give me a chance. Idk what I’m trying to get out of this post.. maybe the secret. I’m really discouraged with my life right now..

P.S. I know I’m pregnant right now and that plays a HUGE factor in job changing but this has been on going long before I got pregnant again..
