Ooh boy, autistic AND adopted? Just one of those can kill somebody.
Bet the bullies outnumbered the supporters!
Well, I am guessing you couldn't get a job because of your social struggles and maybe identity struggles from being adopted, gave up, were a caregiver for years, maybe decades, your adoptive mother didn't teach you anything to prepare you for life because she felt sorry for you, you're now all alone, and now you need help selling. I'm sorry I don't live close by because I have dealt with a little bit of that myself.
Good luck finding a sincere, compassionate person to help you sell your house. If I were you, I'd do the FSBO and just be yourself; the right buyer will come along.
People who are 'creeped out' by you are not worth dealing with. If they are interested, they will try to trick you and deceive you. Bet you've already dealt with those types again and again, haven't you?. All you are responsible for is your intention; perception is their responsibility. I tell you, people LOOOOVE to brand those as socially awkward as conceited or retarded; that wrongful perception makes them feel soo gewd about themselves, you see. Us vs. them thinking.
Sell it yourself, be yourself, you sound like a thoughtful person to me who never had the right treatment or opportunities! Stay strong and come to Boston! Boston ranks highly for autism services! But first. GET.OUT.OF.THE.SOUTH. You'll feel worlds better. Best of luck to you!
