I don't know if you're already working and don't have much time left over. But, when I was a teenager, I got a job in a nursing home. I was very in my shell and had no aptitude, at first, for the job. Then, having to take care of other fragile people changed me a lot.

If you have the time to do any kind of work in healthcare, it might help you to learn to connect with people. You sound like a caring and responsible person. Children's psych facilities are often desperate for staff. As far as I know, there are no special requirements, other than having a clean background check. You wouldn't have to worry about not knowing what to do with these kids. Most people have little idea, at first. But they'ld train you, and you might be surprised at what you could learn.

Consider anything that puts you in a defined relationship with people. Having a role to play and being needed can get you out of your head. Also, you would learn a lot working with people that have serious need for support. If not employment, maybe spending some volunteer hours somewhere . . . even helping serve food in a place that feeds the homeless.

Just a thought.
