I can relate completely.
I've always disliked being ignored by people.
I remember back in high school when teachers would ask us to find a partner for a project.
As always, nobody wanted to work with me despite having good grades. And the worst part was that when there was someone without a partner, instead of working with me, they would form a team of three with an existing pair.
Even worse, during the pandemic, a classmate once sent me a message when I had Telegram, greeting me and saying that I was forgetting about her and the rest of the classmates. I simply responded with:
"I should say that, you all forgot about me." And you know what? After that message, she never responded to me again.
Why do people suddenly care about you despite ignoring you for a long time?
I've tried to stop thinking about making friends and just continue with my life, but, like you, being alone has become monotonous for me, and sometimes I just want to go out and distract myself a bit.
However, being a NEET, I'm a complete stranger in the streets.
I don't understand when people say making friends is very easy, as if they know what a friend is.
When I was a child, making friends was easy. My classmates would talk to me despite my shyness and always invite me to play. All that mattered was having fun.
But now, as an adult, making friends is quite complicated. It seems like I have to find friends "to have a better life," and I say this because my therapist basically told me that. According to her, she says that without friends, I won't be able to get a job or something specific because, apparently, in adulthood, having friends gives you social status...
Even if I try to be social and meet new people, I always feel like a ghost, as they never seem interested in me.
Even though I try to convince myself that I don't need friends and prefer to be alone, I wonder how long I can keep this up...
