In a pluralistic world, there is no such thing as normal anymore. The statistical "normal curve" is dynamic, ever-changing, loopy (pun intended), skewed with varied rates of kurtosis, etc.

And sometimes the "abnormal" people become rock stars, genius scientists, etc. So "abnormal" isn't always "bad" either.

There are many people with limited friendships, including those who are elderly, those who are disabled, those who struggle with mobility, those who are bedbound, those who are homebound, those who are sensitive to light, those who are sensitive to the cold, those who have major physical deformities, those who struggle with social anxiety, those who struggle with agoraphobia, etc.

I think we each find our own niche in life, and sometimes it is hard finding commonality with others. Some people move just to find a way to fit into a group if it's not provided locally. Others find their tribe online.

Some people work so much for a living that they rarely have time for friends, hanging out, or even family. Some of those people might not even care whether they "fit in" or are seen as "normal" or not.

What matters is how you feel. It's not about labels of "normality." Rather, it's about whether or not you want friendships, and how many you can handle. Friendships are relationships, and relationships take energy, and sometimes we're limited on energy. Friendships typically include more than mere acquaintances you see from time to time; they take actual give-and-take, communication, effort, understanding, etc. If you truly want more friends, you can ask your therapist or even others to help. Sometimes the process of asking for help will, in and of itself, create a friendship between you and the person helping you.

If you're okay without friends, than that's cool, too.
