Tourett syndrome

Hey, im not diagnosed yet but I wanted to ask questions since i read a bit about it and i have similar actions. So... I keep feeling like the urges to say or do anything, i feel like i HAVE to do it. I have this uncomfortable feeling inside of my body to do or say something. At home i don't do that because my mom had told me once that im just lying to get attention so im doing my best to stop but i noticed that my anxiety had grew more. Now im at my bestfriend house for month, i feel comfortable enough to not to stop that but it's really strong now. I keep repeating stuff or moving my head to the sides or slap random things. I remember that as a kid i kept repeating the letters k, kr kp because it just felt right. What do you guys think? Am i just crazy or I should go see a doctor? Im sorry if im texting in a wrong group or if my English is bad, that's not my first language...
