Introvert here. Get drained in crowds, being alone in quiet privacy is recharging. Cuz autism et al, most of life has been on edges of crowds, everyone connecting, me confused, alone. Use to feel like a failure, desperate to connect.

Now, tho.... have learned to socialize by osmosis. So if a feel alone, just go somewhere public. Have very active imagination, lot of interests, talk to myself a lot. Danger of social isolation , my thoughts start to narrow, recursive, world gets smaller.

I'm late 40s, no friends, no family, no one to talk to... I think I'm OK about being alone. Or maybe that's self delusion.
