How to make friends as an adult with ADHD and depression?

I know this is an old post and I'm new too but I relate a lot, due to my depression and self isolation because of that, if there's any community groups in your area or if you see a mental health professional they may also be able to recommend groups that are related to things you enjoy, I know depression can often take away the motivation to keep up with hobbies and things you enjoy, but I think maybe a community type group with people your age who experience similar mh issues might be a good option to try. It might even be worth having a look online? There's some groups at an assisted living centre that I used to stay at that I want to go to but am way too anxious lol (walking groups, guitar groups, gardening, arts n crafts etc)

Google some local groups in your area. I do design work (v minor) for a local green task force and have met some nice people. Next door is good for finding local groups. Google a sport or activity + your city. Even if you don't stick with the group you might find someone to get coffee with.

I've found good friends on reddit and VRchat, the internet is full of people looking for friends
