@Former-Member i'm really sorry that your past experiences with building connection haven't been positive, and it makes sense why you'd feel frustrated and tired after trying so hard. i know you mentioned you've tried a lot of stuff out before so let me know if you've already checked this out too:
also i'm not sure if dating apps are something you're interested in but there are some apps where you can disclose that you're neurodivergent, and apps like Bumble let you choose to make friends or date (you choose). if you've already checked these stuff out, then please ignore this!!
i know there can be a range of factors besides mental health too, like your location, compatibility, etc., i'm not saying that making a connection is easy at all, but i am saying it isn't impossible. i guess we all have our own way of connecting, and we just haven't found yours yet. for me personally, i had to reconnect with nature & music before i even began connecting with people. things like people watching helped me slowly gain confidence to even interact with people. you mentioned a disconnection from reality - do you feel connected to anything else? like nature or animals or art or music, etc?
