How to feel better?

Hi, I'm at a point in my life that feels terrible... Pointless?

Immediately after high school, I moved away from my parents and then gradually both sides cut off contact. I started making money, finding a place to live, taking lessons I've always wanted to try and find what I enjoy and fulfill. I'm trying to develop myself. I can spend time with myself. I'm pretty happy. But what now? Now I have everything I could never have imagined. I'm at such an indefinite point. I want to make some more friends. On the one hand, it's simple. You reach out to someone and start talking to each other. Period. But the other one? Where? How? What small talk to lead? I don't go to clubs and discos and shapes. I'm more of the type of person who's going to sit in the park with a book and then go with a friend to play pool or board games.

Or the next question.. The question has been asked - where do you see yourself in ten years? I've been in the adult world for a while now. But I still find it unimaginable to start the business I wanted as a child. Buying a car or a house. That no one tells me: "You shouldn't have to do this because. . ." but I'm more likely to be told: "'Great idea, go ahead!".

Now a light summary of my story and a final question. How did you guys make this transition? Any types of how to process it better?

Thank you for any answers :)
