It seems your need for people is to serve a function that is self-fulfilling. You want people to entertain you when YOU'RE lonely.. to compete against you so YOU win.. to validate YOUR feelings when they're impressed by YOU.. etc.

I see you're not interested in giving much in return, according to this post (I'm not familiar with your story). I see you're not interested in forming meaningful relationships and maybe it's because that would require effort and a more selfless approach, on your part.

I see you get bored easily and like to impress others, and probably already know that once you're in a committed relationship, you will be expected to put effort into it, for someone else. It's also likely your partner will be less impressed by you when they realize how you operate.

I see relationships as a lot of work. It's a learning curve to meet someone else's needs. It takes time and effort to listen to someone else's input, life experiences, and ideas. We do this because we care enough to consider what they have to say.. to be open to their thinking, even if we disagree. I see you're not at all interested in any of this, unless there's some momentary reward for you.

How you live your life is not wrong, as long as no one is getting hurt in the process. It's ok to not want people or have them only in small spurts of time, if you're clear about your expectations and boundaries.

As your therapist said, if you don't have a need or desire to be with a partner, than don't sweat it. Lonely? There are many competitive things/hobbies you can do to get attention and void those momentary feelings of loneliness.
