I would tend to say I am a little unhinged or "off" most people think i am crazy or something. I think there are levels, I had friends who were popular and normal in the past and dated normal girls, some very good looking, this was a long time ago. I think if you can be interesting and a little nutty, and say original things or creative things or have a sense of humor, a lot of people can overlook your wackyness. I mean if you are just babbling to yourself and have an I.Q. of 35, I doubt anyone would associate with you from "normal" society. Most people who live in that world are incredibly boring.
Most people in general are very boring and stale, but people who are a little weird or strange are generally a lot more interesting than popular people who have the normal lives: PHD, traveled to 15 countries, enjoy fine dining, ski or have country homes, married and divorced, have read hundreds of classic novels, follow politics closely, dress in preppy clothes that are all color coordinated. Those people, despite them having their S together, are just all the same and somehow even with their life experience, are also extremely limited somehow, if you engage them in a conversation.
I have all the familiar symptoms of someone who has mental illness but I am convinced I am not. I am not that limited where I can function and work and speak well or write well despite anxiety. I don't ever even see the point of anyone admitting they have mental illness to anyone, that is like telling someone, "I am retarded and an idiot and crazy" I would just say I have general anxiety and my nervous system is wrecked from quitting medication cold turkey and years of smoking weed and drinking (20 years ago). If I literally could not function at all, then i guess I could admit to having mental illness.
Social anxiety I could care less about admitting to anyone basically, as long as I don't make a big thing about it. If I admit that to someone and then get cagey and defensive then of course it will sound worse than it is. If I say it casually who even cares, no one really even knows what it is really. In a work environment I wouldn't even admit that I breathe air to anyone. Saying you have depression is another disaster which I don't think anyone should ever really admit to someone, at least who they don't know well.
I don't even understand what the hell depression is. I was suicidal for years on and off and i still didn't consider myself depressed. I was sad a lot in my life, and hopeless. Saying you are depressed is like a label that can even excuse people from moving on from their problems. My life has very little meaning now and I am kind of dreading my life going forward but i wouldn't consider myself "depressed"
Admitting you are depressed is probably close to as bad as saying you have mental illness. Mental illness sounds a lot worse I guess, but saying you are depressed means you are just sick of everything or a loser or whatever
Anyway i went on too long but i would mention to someone in a support group anything you want, or online, just basically admit nothing to the public
