How do i get a job?

I am very shy and I dont like to go anywhere without my mum. I want to get a job but I dont want to leave the house on my own. I will only go somewhere on my own with my dog or with mum only. I’ve been bulied all my life and that has stopped me leavin’ the house and going outside because we have bad neighbours aswell which makes it more harder for me. How do I get out of the house without worrying about them and things?
