Full honesty though as someone who was going through something/depression/purposelessness back in 2012 and found the world of DnD, Magic the Gathering and Tabletop games it can be dangerous to get into a hobby like DnD because you may end up liking that life over your actual one. Took me 4 years to get out and do something because everyone within that community also had lives they didn’t want to get back to and kept enabling each other.
@QuietStorm Facebook is your best friend (only in this situation). Just search for Dungeons and Dragons/RPG + the area or city you live in. You could also search for Local Game Stores or Magic the Gathering stores near you as both MTG and DnD are owned by the same company and usually supported together.
