how do I help my motor tics?

how do I help my motor tics? I am a severe stutterer and I am insecure about my also severe tics when I have blocks. I close my eyes very hard and tilt my head all the way down and my arms can also move involuntary. This also makes things like talking and walking and talking while holding things like hot drinks very difficult as well as humiliates me (I assume I look pretty ugly as it gives me a double chin). This issue has only really appeared as my stutter has gotten worse the past two years or so. Has anyone else dealt with this? How can I help it?
