Check if you qualify for assistance. I know in New York they have programs to help adults with disabilities. As much as we don’t like to think of ourselves as disabled, a stutter does qualify as a disability. So step 1) get financial assistance so that you can go see a professional about your mental health. And speech therapy. Step 2) see if your state offers job training and job placement. Try a career in tech or a trade job. Step 3) do NOT let your mom keep you from living your life. You did not ask to be born. She made the choice of having you and raising you. You DONT OWE HER ANYTHING! you did not ask for this situation. Once you get on your feet, then you can extend a hand to help your mother out but do not let her drown the both of you.
