How can I stop fidgeting?

[Lulu02]

I was watching a video my friend took of me and I noticed how badly I was fidgeting in it. It made realise how everyone else is seeing me as it is so obvious and quite annoying to watch. I have two main fidgets, one being shaking my leg and the other sucking and smelling my hair (I know it’s gross but please don’t judge). I’d say the fidgeting takes up 60% of my day and it tends to occur when I’m bored, trying to focus or when I’m anxious or stress. Ive been fidgeting since I was a baby, starting with sucking my thumb up until the age of 8, twirling my hair, playing with my earrings. I know it’s because I have ADHD but I’ve tried so many things to stop it but I just can’t. If anyone has any suggestions on how to stop could you please let me know because really self conscious about it especially with the hair thing being so gross.
