Humm... well, if it's advice you're looking for, based on the information you've provided, you could look into courses you can take re: social skills. As well, joining a "meetup" group may help you as well. Hanging out with like minded people can make us feel included and also can help us work on our social skills in the process.

My hobbies are varied. My personality is ENFP (Myers Briggs MBTI). So I am the most introverted of the extroverts. Therefore, because of this, I have extroverted and introverted hobbies. Here are a few of them:

1) Singing in my band
2) reading and writing
3) art work
4) volunteer work in my community
5) volunteer work with a suicide prevention/depression help line
6) redoing furniture / refurbishing old antiques
7) Gardening in the yard of our new house - there's lots to do!
8) a girls night with a few of my gal friends every week where we do art and go out for a meal afterwards

So, as you see, it's a combination of extroverted and introverted time - Which matches my personality. But everyone is different. What do you think would be hobbies that would match your personality?
