They are both psychiatric abnormalities and they make it harder to communicate with some people.
I like working alone projects wise but as you say, the company of others, if you like them, is healthy, even if you are autistic or schizophrenic.
What I do and think helps is:
0. Tell people about it because it makes them more understanding usually and I found they are also interested in hearing details about it, guess for them it is like watching a documentary :)
1. Laugh about it with them. When people laugh they feel happy and knowing that you made them laugh makes them like you.
It also makes them feel less nervous and uncomfortable and for me, at least, it also makes me feel better when I make jokes.
My psychiatrist also thinks I am correct about this.
Also, might be a good thing to prepare yourself for the option this may not work out well and try not be disappointed by it.
Luck,
