idk what's happening to me and I'm kinda scared

I've been having tics since this July. they started after a pretty bad episode of bullying/body shaming. I read somewhere that tics weren't necessarily tourettes, but could be related to anxiety, so I asked on a mental health subreddit but no one replied. I'm a teen, and my parents still haven't noticed.

the tics are mostly shoulder and head movements, very few times vocal. I could go a few days without them just like a day having many. it depends. they also arrive more with cold weather.

am I valid? idk what to do.
