What do I do if my family doesn't support me???

What do I do if my family doesn't support me??? 16M. In situations like this, family emotional support is usually vital, but what happens if you don't have any? My parents are very traditional and they hate the idea that their son stutters. I'm afraid to talk to them because every time I do, and I stutter, they insult me and make me feel useless. I remember once, leaving school, my mother came to pick me up. She was in a big hurry and asked me something, I took a long time to answer and she called me "retarded." That word felt like a stab in the liver. To avoid crying in front of her I told myself, “it's ok, she's had a long day.” I'm sure my parents think I'm mentally ill. Am I mentally ill? Honestly, I don't know. But seriously, what can I do? I have no one. I went to a psychologist and a speech therapist, but they didn't help me. I'm constantly trying to distract myself from this disgusting, sad, and miserable reality
