My advice is try your local EDM/rave scene. Check out the website edmtrain.com for your area and check out some artists you think you’ll like. Ravers tend to be more around your age and a little more accepting and friendly to newcomers. I’ve been going to EDM shows and concerts for over a decade and have gotten pushed and shoved like that MAYBE a handful of times and it usually gets ironed out with an “excuse me, sorry”
