The symptoms I have could be associated to Huntington's disease?

I am 18 years old and reading about this disease I realized that I have many of its symptoms.
At the age of 16, I developed a craze to pull my hair in a convulsive way, my level of attention has dropped a lot (I notice this from the mathematical tasks in which I make many distraction mistakes even though I am sure that in that moment I am concentrated), I am affected by muscle stiffness (when I am subject to a stressful situation such as a task or a test my legs and lips are always tense) and I have become prone to develop addictions especially from food.
However, in recent times (for a few months now) I can control the convulsive movements and addictions but I cannot say the same for muscle stiffness and attention.
I would like to know if, for such a picture, there is the possibility of some correlation with the disease and therefore if it is worth performing a genetic test or not.
Thank you very much!

Hi, Huntington's Disease is genetic and therefore the presence of the disease is unlikely in the absence of other affected family members. It is not recommended to undergo any genetic testing before a thorough medical examination.
