I want to try and answer this without reading everyone's replies first.
I imagine I would have an ok job or career that was somewhat enjoyable and satisfying, sometimes frustrating and so on also. I imagine it would pay enough for accomodation, some hobbies n social life. Also I would even have some holidays!!!
I would have my own flat or share with a partner. It would be a colourful home with plenty of artwork. I would probably still be quite skilled at killing plants :D
I would have some friends, I would not be terrified of people, of being seen, I would have a fraction of the shame and mental health problems I do now. I would be able to relax around people and have fun
I would have some relationships, that were more or less as successful and long lasting as anyone else's - and periods of being single too. I would enjoy the relationships that were enjoyable, and be happy to end this that weren't.
I would become eccentric in my old age :)
