You’re latching on to one half ironic thing I wrote so you can prove that something is seriously wrong with me? Maybe you need to talk to a professional? Lack of object permanence is one of many symptoms of autism. It makes my life a little more difficult because I sometimes have to remind myself that I can and should continue to connect with people not in my immediate surroundings. I do not literally believe they disappear and I’m sure my other answers must reflect somehow that I’m not a delusional solipsist. But hey, whatever supports your self importance.
Sorry for being rather acidic, I got hung up on the “this one post tells me enough”, it sounded arrogant to me and my answer to it was over the top and unnecessarily unfriendly. Thank you for trying to help and giving advice. I really hope my reaction doesn’t put you off trying to help others online in the future!
