How the fuck do you talk to people?

So, I can't help but feel like I'm coming across as boring and uninteresting. I'm trying to raise my game around people, bring more positive emotion, and lightheartedness, and I concede some of it is just in my head and that in itself perpetuates the problem, but I'm still really forcing conversation, and running out of talking points. I start panicking around people, my emotions are on edge, and I struggle to control them. All I want is to really enjoy the other person and the conversation and there's this fucking wall in the way I've built. I've been working my ass off to try and stay positive, force myself to be more social, and I give less fucks now than in the past but I still feel personalityless. I'm subbed to r/socialskills among others already.

There was a 6 month stretch of my life where I was incredibly social, confident, could talk about anything and make people laugh. I loved myself, and it was in part because of the reactions I was getting, but mainly because I felt I was just showing others the real me. I've been trying so hard to get that back state of mind but I've come up empty handed chasing. I'm in a place now where I just want to improve, I'm over the negative bullshit, I'm over the self-pity, I just want to be fucking awesome and have people sincerely enjoy my company. What the fuck can a guy do?
