Struggling with being on the spectrum

Hello all; I’m 21 years old and I’m on the spectrum. Last two years I’ve been struggling to deal with myself and my behaviour has gotten really bad, I’ve started to get really aggressive and defensive over it and I can’t keep control of myself during difficult times and places. I’m reaching out for some help as I can’t carry on the way I’m going. I feel the label of Autism is taking over my life when I should embrace it and not let it get in the way of everyday life. I need to take action to improve my wellbeing and overall happiness, what steps should I take to move forward?
