Choosing where to post
Questions do best in r/Anxietyhelp, the community on this list that is built around advice and help (around 72 posts a day). Asking the same thing in r/Anxiety often gets it removed or lost among the 157 daily posts. Competition for attention differs a lot: r/adhd_anxiety has 92.5K members but only about 5.0 new posts a day — roughly one new post for every 18.5K members — while r/Anxiety gets about 157 a day, one for every 4.7K. A strong, well-made post therefore has more room to be seen in r/adhd_anxiety; r/Anxiety is better when you want quick replies.
Big subreddits give a post the widest audience, but they also bury it quickly; the mid-sized communities on this list are usually friendlier for questions and first posts. Always read the rules in the sidebar first — each community is run by its own volunteer moderators. Our guide to searching Reddit explains how to dig through any of these communities, and the subreddit info tool gives you the stats of one we don't list.
