Why Do I Repeat Words Or Stutter? Why Has It Started Lately?

I COMMONLY repeat my own words or spell them out repeatedly. I can t move onto another word until I have completed the word as desired (sometimes it goes on for MINUTES). The words at the end of my sentences. Whether I was thinking something, saying something, or typing/reading something. Sometimes I even repeat others words. It just happens. I can control it but if I don t do it, I feel weird or make humming noises or clear my throat . Sometimes when I do do it, afterwards, I ll make a humming noise. Lately it s been REALLY bad. I ve been doing it like CRAZY the past two day. And right now, I haven t gotten through this whole entire thing I , typing without doing it! I ve heard of tics and are these tics? I also have more habits other than theses that I have researched to be tics . I ll be 16 tomorrow (I m a female) and this had been happening for almost maybe a year now. Other things have been happening since I was maybe about 8-12 years old. What wrong? Should I tell my mom to take me to a doctor? (tried telling her a year back but she didn t believe me and told me to stay off the internet. Which is just ridiculous because I CAME on the internet to research what had been happening to me for YEARS.) Please help me and give me some insight because this is driving my MAD. Also, what kind of doctor handles this? Thank you.
