If you’ve recently developed an appetite for D&D, and are excited to play again or play for the first time, your going to need a group to play with.
Personally, before I was able to play my fist game I watched hundreds of D&D videos on YouTube. Luckily for me, my friends group were interested in playing too. Make sure to ask your friends whether they would be interested in playing D&D, you never know.
This might not be an option for you, so I suggest that if you try and find people like you, most likely, nerdy people.
The way I suggest you do that is to look online on social media or websites like Meetup for tabletop role-playing groups or meetups. If their are none in your area, look for other activities you enjoy so you can find people like you, this actually could be anything from a Tabletop gaming meetup to a salsa dancing class, the more friends you make, especially over the nerdy hobbies, the more likely you are to find people who already play D&D or would be willing to play for the first time. Lets be real, it takes some real balls to join a new group for the first time, but, in all honesty you are not going to find a D&D group by sitting alone inside. (although with the coronavirus maybe that’s not such a bad idea)
It’s a long shot, but there may be somewhere in your area that runs adventurers league, I have no further comment on adventurers league since I don’t have it where I am so it might as well not exist.
